In the middle of matter, small and unseen

There's an atom, a universe even

In solids, liquids, gases they combine

In every atom that we find

Around, in orbits wide and free

Electrons dance, lively and free

Their paths, like planets around the sun

Holding protons and neutrons combine as one

Invisible architects, making our sphere

In every leaf, every tear

Atoms, small and unseen

Are the foundation on which life does lean

"The Structure of Matter

I understand that isotope, atomic number, and atomic mass are different.

The isotope have the same atomic number, but have different atomic mass, and the atomic number of an element is equal to number of protons and electrons, and the atomic mass is the quantity of matter contained in an atom of an element. And I understand that Dmitri Ivanovich Mendeleev is the one who created the Periodic Table.

I realized that there's so many scientists contribute on developing atom and there are five(5) atomic model. The first atomic model was proposed by J. Dalton and this model often referred as a Billiard Ball model, the second atomic model was proposed by J.J Thomson the Plum Pudding model, which had a negatively-charged electrons embedded within a positively charged called "soup", the third atomic model was proposed by E. Rutherford the Nuclear model in this model Rutherford demonstrates the existence of a positively charged nucleus that contains nearly all the mass of atom, the fourth atomic model was proposed by N. Bohr the Planetary model it shows the fixed circular orbits around the nucleus for electrons, and the fifth atomic model was proposed by E. Schrodinger the Quantum model he says that electrons move around the nucleus in a "cloud" not orbits.

I learned a lot about the stucture of atom,especially on the scientists involved in its discovery.I understand that atom is the smallest unit of matter,it can be broken down without realeasing any electrically charged particles.Through the discussion of this topic I also earned about the tree subatomic particles of atom which is proton,electron and neutron.What I realized and understand about tese these subatomic particles is that proton its sign is (p+) indicating that it is a positively charged subatomic particle,it is located in the nucleus of the atom.Proton is discoved by Ernest Rutherford.The electron has a sign (e-) indicating that it is a negatively charged subatomic particle.Electron is dicovered by J.J Thomson. As for the neutron (n°) I learned that it was a subatomic particle located in the nucleus of atom that has no electrical charged and it was dicovered by James Chadwick. Although I learned a lot in this topic I still have a question for my teacher about the formulas in determining the number of proton,neutron and electron.

There is so much that i have learned in our previous lessons. The atom with its interesting features. It is made out of 3 fundemental particles, the protons, neutrons and the electrons. The protons are the positively charged particles meanwhile the electrons are the opposite, it is negatively charged whereas neutrons are neutral, meaning they do not have charge.

The structure of atom consists a nucleus, it is composed with protons together with neutrons surrounded by electrons, orbiting energy levels.

Also made me learn, from the first even to the last element of the periodic table.The Atomic mass and its atomic number. The number of the protons and electrons are the same as the atomic number, meanwhile you'll have to subtract the atomic number from the atomic mass to get the number of neutrons.A realization that i have encountered while writing this is was that, the atom had alot of things connected to it. Everything in our surroundings are made out of atoms, even us human beings. Without the atom existing, everything or everyone in our planet wouldn't have existed. I have no other questions that i would like to ask my teacher because my teacher has discussed about this lesson well and clear that i have understood our lesson properly.

It has a nucleus made up of protons (positive particles) and neutrons (particles with no charge), while electons (negative particles) move around the nucleus. The word atom is derived from the ancient Greek words "atomos" which means "indivisible". Plenty of scientists had contributed about this — structure of atom, shared and expand their knowledge about it to fully explain how the structure of an atom works and what is in it.

understand that the atom, often referred to as the building block of matter, is composed of three main parts: protons, neutrons, and electrons. Protons and neutrons form the nucleus of the atom, located at the center, while electrons orbit around this nucleus in specific paths called orbitals.

I realized that the structure of an atom is not as simple as it seems. Electrons do not orbit the nucleus in simple circular paths, as I initially thought. Instead, they exist in a cloud-like region around the nucleus known as the electron cloud. The exact position of an electron in this cloud cannot be pinpointed; we can only predict the probability of finding an electron in a  certain region.

My science teacher taught me a lot, she taught me a lot of interesting things that i wish i knew sooner. But there are one lesson that really catches my attention...Atoms!

Although to some students, they find atom boring? Well they have their own opinion and i have my own too.

Going back from the day that my teacher taught me all the lessons about atom. Now let's just get straight to the point and not waste anymore time.

The story of the atom is a very long one and the first theories of the atom weren't even based on experiments but conjecture of what they know already to make it make sense. The first theory was made by Greek philosopher, Democritus. He came up with the word atom, He asked this question: “If you break a piece of matter in half, and then break it in half again, how many breaks will you have to make before you can break it no further? Democritus thought that it ended at some point, a smallest possible bit of matter. He called these basic matter particles, atoms”. Scientists have been trying to figure out the structure of the atom since the Greek era, 2000 years had passed and no one tried to continue work on the Atom. The first theory that was based on a more scientific approach that seemed to fit was by John Dalton, an English chemist and his “Atomic Theory” in 1803. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties. John Dalton's quote, "An atom, with all its parts, has exactly the same weight as when it was created," reflects the fundamental principle of the conservation of mass. Atoms were thought to be the smallest possible division of matter until 1897 when J. J. Thomson discovered the electron through his work on cathode rays. A Crookes tube is a sealed glass container in which two electrodes are separated by a vacuum. When a voltage is applied across the electrodes, cathode rays are generated, creating a glowing patch where they strike the glass at the opposite end of the tube. Through experimentation, Thomson discovered that the rays could be deflected by electric fields and magnetic fields. He concluded that these rays, rather than being a form of light, were composed of very light negatively charged particles. Thomson called these "corpuscles", but other scientists called them electrons, following an 1894 suggestion by George Johnstone Stoney for naming the basic unit of electrical charge.[38] He measured the mass of the electron to be 1,800 times smaller than that of hydrogen, the smallest atom. Electrons are so light yet carry so much charge that Thomson concluded they must be the basic particles of electrical effects. Thomson was trying to explain electricity but his theory entailed that the atom is not the indivisible entity scientists thought it was. A negatively charged part of the atom splits off to join with an adjacent atom in the action of an electrical current. When electrons do not flow their negative charge must balanced out by some source of positive charge within the atom so as to render the atom electrically neutral. This led to what became known as the plum pudding model, which imagined the electrons embedded in a sphere of positive charge like bits of fruit in a Christmas pudding. Now some of you atom fans are probably wondering, now that we know who discovered electrons, but what about neutrons and protons?

Now how was Proton Discovered? For short, i will just summarize the main article. In a gold foil experiment, Rutherford bombarded alpha particles on an ultrathin gold foil and then detected the scattered alpha particles on a zinc sulphide (ZnS) screen. According to Rutherford's observation, Most of the alpha particles were not deflected; they passed through the foil. Then what about the neutrons? The British physicist Sir James Chadwick discovered neutrons in the year 1932. He was awarded the Nobel Prize in Physics in the year 1935 for this discovery. James Chadwick fired alpha radiation at beryllium sheet from a polonium source. This led to the production of an uncharged, penetrating radiation. This radiation was made incident on paraffin wax, a hydrocarbon having a relatively high hydrogen content. The protons ejected from the paraffin wax (when struck by the uncharged radiation) were observed with the help of an ionization chamber. The range of the liberated protons was measured and the interaction between the uncharged radiation and the atoms of several gases was studied by Chadwick. He concluded that the unusually penetrating radiation consisted of uncharged particles having (approximately) the same mass as a proton. These particles were later termed ‘neutrons’.

Now these are not all discussed by my science teacher, this is my understanding and researches about the theory of the atom. With this, i now have no other questions regarding about the theory of the atom. Without my science teacher guiding me through this lessons, my knowledge wouldn't be as far as i know today.

I was able to broaden my knowledge about atom, its history and structure. But of course, i wouldn't be able to learn this much without the help of our science teacher who is also our class adviser and the given tasks in order to deepen our knowledge more about atom. That's why today, I am very confident and excited to share everything I have learned about atom, mainly about its structure. But first what is atom?

A greek philosoper with the name Democritus was the one who formed the idea of atom which gave other scientists ideas and was able to fully discover and understand atom. Their incredible discovery is now taught to students like me. Based on everything that i have learned, the atom is the smallest unit of matter that can be broken down without releasing any electrically charged particles. Atom is the fundamental building block for chemistry. Atoms are constructed of three sub-atomic particles. These three sub-atomic particles are called proton, electron and neutron. Proton is the positively charged subatomic particle located in nucleus, the center of an atom. Electrons are very small negatively charged subatomic particle that orbits around nucleus. Neutron on the other hand is the subatomic particle located in nucleus that has no electrical charged particle. Each subatomic particle was discovered by different scientists. But how do we determine the number of protons, electron and neutron? It's actually easy and simple as long as you have a modern periodic table which can make you easily determine the number of protons, electrons and neutrons. There are a total of 118 elements in periodic table. Each elements have different atomic number and atomic mass. They are arranged in an increasing order of their atomic number. Atomic number is the number of proton, and the number of proton is the number of electron. But how about the number if neutron? Notice that each elements have different mass, in order to determine the number of neutron, we only have to subtract the number of proton to the atomic mass of its element. Simple am i right? But in some other cases there are elements that have the same atomic number but different atomic masses which are called Isotopes.

Learning the atom and its structure is very easy and simple. It seemed complicated at first but i believed in myself that i can learn it even if it takes me step-by-step process which takes patience and determination. The journey of learning atom was difficult but at the same time, it was also very fun and interesting.

With the help of our science teacher, i have no other questions concerning about atom and its structure.

The structure of matter can vary depending on its state and the type of atoms or molecules that make it up. In solids, atoms are tightly packed together and vibrate in place. In liquids, atoms are more spread out and move around each other. In gases, atoms are very spread out and move freely in all directions.

I realize Atoms, which are made up of protons, neutrons, and electrons, are the building blocks of all matter. Chemical energy is a type of potential energy that holds atoms and molecules together. Matter is defined as everything that has mass and volume (takes up space).

I learned so many things on this lesson. From the first person who gave the idea of the existence on an atom, to the last element in the periodic table. The topic the was fixed to my mind was about the structure of an atom. As a normal student that has not that much capability of understanding anything without the help of others around me, there are times that I didn't understand the lesson the much. When I searched about this topic in the internet, I did not find it difficult to understand, instead I find it interesting that discovering atom was years from now and how the discovery of atom was developed over time. But first. What is an atom??🧐

Atom is the building block of all matters or anything the takes up space and has mass. Atom is also  the smallest particles that matter can be broken down into. The structure of this is really small and it's the source of the elements in the periodic table. At it's nucleus, there are positively charged protons and neutral neutrons. It is surrounded by electrons in it's orbitals or energy levels which levels the nucleus. The number of atoms are also used in the positions and orders of  the modern periodic table of Dmitri Mendeleev which Is called the atomic number. The atomic number is the number of protons and electrons in an atom. The elements in the periodic table also have the number of protons and neutrons  combined. These are what we call the atomic mass. So it means if we subtract the atomic number and the atomic mass, we will know the number of neutrons. These are the formulas:

Atomic # = no. of protons and electrons

Atomic mass- atomic# = no of neutrons

At first I thought that I wouldn't understand this lesson just because I didn't understand it at the first place. But when I studied the lesson, it was actually a topic that requires more interest before you understand it. So in this lesson, I learned that you want something that you have never had, then do something you have never done.

The structure of atom is really fun to learn and discover, i learned a lot and discovered a lot of things. It's really interesting because it's so many scientists that has a lot of contributes in atom. Furthermore, i already know some elements of periodic table because we already tuckled it. Our science teacher taught us very well that's why i really understand it.

I also realized that it's so easy to determine the protons, electrons and neutrons. I also learned that the atom is the smallest unit of matter, all matter is made up of atom. In addition, the word ATOM come from the greek word “atomos” atomos means, indivisible. Our science teacher taught us too about the meaning of isotopes, so isotopes is same atomic number but different masses.

In summary, studying the structure of atom is really important because we can share it to anyone that interesting to learn the structure of an atom or we can share it to another generations. I don't have any clarification or questions to my science teacher regarding the topic because i really understand it.

first I really understand the lesson because of our smart adviser in science, for being good at teaching and for giving us efforts. I understood the lessons we took about The properties of matter, Development of atom, The elements of periodic table, arrangement of the element and last The periodic table.

I understand that matter is anything

that takes up space and can be weighed. In other words, matter has volume and mass. There are many different substances, or types of matter, in the universe and the six types of phase changes of matter and they are evaporation (liquid to gas), deposition (gas to solid), condensation (gas to liquid), sublimation (solid to gas), melting (solid to liquid), freezing (liquid to solid. And I also understood that the atom is the most fundamental and smallest part that can exist of an element and the molecules are two or more atoms chemically bonded together .and this includes protons, electrons and neutrons. I also understood the development of atom because this is where we identify who are the contributors who helped and we discovered to know what they did to the atom and we can take it to the next field, first contributor , Democritus -created the first atomic model, Aristotle- developed theory that all substances that composed of four elements, John Dalton- proposed his modern theory of atom, JJ Thompson- discovered the plumpudding model of the atom, Ernest Rutherford - model of atom, neils bohr - presented a picture of an atomic structures and etc contributors. And last we discussed that fully  understood is the Element of the periodic table, the elements of periodic table has 118 elements and more and it also has contributors who discovered the element of periodic table this is Dmitri Mendels and others. And they have protons, electrons and neutrons that were also discovered by contributors. Protons-positively charged, Electrons -negatively charged, and Neutrons -subatomic particles located in the nucleus that have no electrical energy. Atomic number is the number of protons and electrons. Mass number is when the mass number and atomic number are subtracted and it is equal to number of neutrons. This is all that I learn and understand from what our good adviser MAAM MARISSA taught us.

I also realized that what we have studied in science is very important, it will help us in the next generation or in the next field that we will walk. It was very easy for me because I understood all the lessons or teachings that we should put in our minds to help us.

Based on our lesson that our

teacher discussed to us, Atomic Structure is a fundamental part of Chemistry. Knowing about the electrons, neutrons, protons can help you understand what’s going on in chemistry. This is very useful in future studies.

I understand that, Electrons, neutrons and protons are very important.

In the past, people think that atoms are the smallest unit that is indivisible. From the word itself, the word “atom” comes from “atomos”, a Greek word meaning “indivisible”. John Dalton proposed an atomic theory. Atom is the smallest part of the element having the chemical properties of the element.

Atomic structures are visual demonstrations used to help understand how an atom looks like on the interior in the inside and what it consists of.

And also i realized that, Atoms are made up of protons, neutrons and electrons. Protons are positively charged, neutron is neutral while electrons are negatively charged. Protons and neutrons are in the middle part, which is the centre of an atom – very tiny, and extremely dense. Protons and neutrons packed tightly together in this centre, called the nucleus. The overall charge for the proton will be positively charged. That’s because protons and neutrons are making up the nucleus, in which protons are positive and neutrons are negative. For electrons, they are found in the empty spaces. Electrons are very light in mass. They move around the nucleus.

Based on the previous lessons that we tackled, i learned a lot of new things and glad to discover a few scientists that have a plenty distribution on our society. One of the lessons that we discussed was all about of atom, let me give my own understanding and thoughts about atom. Atom is the smallest particle of  an element. Addedly atom is the building block elements of matter that's why matter is made of indivisible building blocks known as atomos. (Atomos in Greek means indivisible).  This indivisible building block of which all matter was composed became known as the atom. As we explore the diverse world of matter, we will also discover a few scientist such as Ernest Rutherford, Neils Bohr, James Chadwick, J.J Thompson, John Dalton and many more. English scientist J.J. Thomson's  led to the discovery of the negatively charged electron and the first ideas of the structure of these indivisible atoms. Furthermore, Thomson proposed the Plum Pudding Model, suggesting that an atom's structure resembles the favorite English dessert - plum pudding. The raisins dispersed amidst the plum pudding are analogous to negatively charged electrons immersed in a sea of positive charge. In  Ernest Rutherford's discovery, he discovered the famous gold foil experiments led to the nuclear model of atomic structure. Neils Bohr improved upon Rutherford's nuclear model by explaining that the electrons were present in orbits outside the nucleus. The other scientist remaining contributed a lot especially in improving the placement of the protons, neutrons, and electrons and their physical appearance in microscope. As we all know that nucleus was/is surrounded by neutrons and protons and at the outside are electrons. In exploring this topic, we will also going to know the phase changes of matter, which are deposition, condensation, evaporation, freezing, melting and sublimation. Deposition is when substance change directly from gas to solid, condensation is when something  from gas change to a liquid, evaporation is when from a liquid to a gas, freezing is when liquid turns into a solid, sublimation is when solid turns into a gas and lastly, melting is when a solid turns into a liquid. Despite of all this lesson, it's also essential to  know and have a better undestanding in predicting the chemical behavior of an element in periodic table, it will help us to have a  better understaning and to identify the no. of atomic #, atomic mass, the electronegativity and etc.

As the years passed, understanding this particular topic is really important in our generation. We can also use and learned what we understand to those people who doesn't have any ideas in this topic. _ (my statements contains several grammatical errors that need to be corrected for clarity)

I understand that everything is made out of an atom, an atom is the fundamental building block/structure of anything that takes up matter or space.The structure of an atom offers profound insights into the fabric of reality. At its nucleus, the interplay between positively charged protons and neutral neutrons governs an atom's stability and mass. This core, bound by the strong nuclear force, anchors the atom's identity within the vast expanse of the periodic table.

Surrounding this nucleus, electrons whirl in orbitals, their paths dictated by quantum probabilities rather than deterministic trajectories. These subatomic particles, characterized by their negative charge, occupy discrete energy levels within electron shells, shaping an atom's chemical properties and reactivity.

Moreover, the atom's structure unveils the intricate dance of elemental diversity. Variations in the number

I realize that Investigating the atom's structure unveils a myriad of intriguing features. The nucleus, located at the atom's core, contains positively charged protons and uncharged neutrons, held together by the potent strong nuclear force. This tiny nucleus, despite its diminutive size, holds the majority of the atom's mass, influencing its characteristics and behavior. Beyond the nucleus, electrons navigate in intricate orbits, governed by the mysterious principles of quantum mechanics. These negatively charged particles reside in specific regions called electron shells, with each shell accommodating a set number of electrons based on their energy levels. Quantum theory reveals that electrons do not follow fixed paths, challenging the concept of their precise location.

Atom

In the realm of knowledge, I've embarked,

Exploring the structure of atoms, I've sparked.

Through lessons and study, I've come to see,

The wondrous world of atomicity.

Atoms, like tiny universes, they unfold,

With particles and forces, a story untold.

Protons and neutrons, in the nucleus reside,

While electrons in shells, gracefully glide.

I've learned that protons carry a positive charge,

While neutrons, neutral, in the nucleus enlarge.

Electrons, with their negative charge, they roam,

Journey to the mysterious place of the atom.



Over time, most of today's youth do not know how to view the past, such as the contributions of scientists, the origins of things, and many others. But in the books written by those with potential, most of them help young people expand their knowledge.

And when I studied in the assigned science about the structure of atom, I got a lot of new knowledge and lessons.

I learned in this lesson that the atom is the source of all the elements in the world and I also learned that the elements in the periodic table are arranged according to their characteristic type group or family and period. And above all, the scientist who invented the periodic table is Dmitri Mendeleev.

I also realized in this lesson that it is important for us to learn the symbols of protons, electrons, neutrons and mass of elements because these elements may be in contact with us on a daily basis, may be eaten or used.

And in closing the previous lesson I have no questions. But I will be ready and I will wait with all my heart for the lessons to come.

I understand about structure of an atom is the atomic structure of an element refers to the constitution of its nucleus and the arrangement of the electrons around it. Primarily, the atomic structure of matter is made up of protons, electrons and neutrons.The proton and nuetron make up the nucleus of the atom, which is surrounded by the electrons belonging to the atom. The atomic number of an element describes the total number of protons in its nucleus.

Ernest Rutherford is known for his pioneering studies of radioactivity and the atom. He discovered that there are two types of radiation, alpha and beta particles, coming from uranium. He found that the atom consists mostly of empty space, with its mass concentrated in a central positively charged nucleus.

In addition information an isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

In embarking on the exploration of atomic structure, I've come to understand that the atom, the building block of all matter, is composed of three primary subatomic particles: protons, neutrons, and electrons. Protons and neutrons reside within the nucleus at the atom's center, while electrons orbit the nucleus in distinct energy levels or shells.

I realize that the arrangement of these particles within the atom is fundamental in determining its properties and behavior. The number of protons defines an element's identity, known as its atomic number, while the sum of protons and neutrons gives rise to its mass number. This understanding sheds light on the concept of isotopes, where variations in neutron number result in atoms of the same element with different masses.

Furthermore, I've come to appreciate the significance of electron configuration in dictating an element's chemical reactivity and bonding tendencies. The distribution of electrons within specific energy levels follows established principles, such as the Aufbau principle, Pauli exclusion principle, and Hund's rule, ensuring stability and minimizing energy within the atom.

As I delve deeper into the lesson, I realize the importance of the periodic table as a powerful tool for organizing elements based on their atomic number and electron configuration. This systematic arrangement facilitates the prediction of an element's properties and its chemical behavior, providing invaluable insights for scientists across disciplines.

In this journey of discovery, I recognize the complexities of atomic structure and the interconnectedness of its components. While my understanding has grown, I acknowledge that there is still much to learn and explore. Each new insight deepens my appreciation for the intricacies of the universe at its most fundamental level, fueling my curiosity and driving me to uncover more about the mysteries of atomic structure.I wish to ask my teacher nothing because my teacher discuss it properly.

My understanding of the structure of atoms. Atoms are incredibly small particles that make up everything around us, from the air we breathe to the food we eat. In this essay, we will explore the basic principles of atoms and their importance in science.

To begin with, an atom is the smallest unit of an element that retains the properties of that element. Atoms are composed of three subatomic particles: protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The nucleus of an atom contains protons and neutrons, while electrons orbit around the nucleus in shells or energy levels. The structure of an atom is a fundamental concept in chemistry and physics that provides a framework for understanding the behavior and properties of matter at the atomic level. The electrons of an atom are found in orbitals surrounding the nucleus, and they have a negative charge. Electrons are much smaller and lighter than protons and neutrons, and they move in a cloud of probability around the nucleus.

One of the key ideas about atoms that I learn in grade 8 is the concept of the atomic number and mass number. The atomic number of an atom is equal to the number of protons in its nucleus, while the mass number is equal to the sum of protons and neutrons. The elements on the periodic table are arranged in order of increasing atomic number, with each element having a unique number of protons.

Furthermore, i also learn about the structure of the atom, which includes the electron configuration. Electrons are arranged in specific energy levels around the nucleus, with each level being able to hold a specific number of electrons. The electron configuration of an atom determines its chemical properties, such as its ability to form bonds with other atoms, Also students learn about the periodic table, a tabular arrangement of elements based on their atomic number and chemical properties. The periodic table helps students understand the organization of elements and their relationship to one another. They learn to identify elements based on their atomic number, symbol, and atomic mass.

In addition to the basic structure of atoms, my learning about isotopes and ions. Isotopes are atoms of the same element that have different numbers of neutrons, leading to variations in mass number. Ions are charged particles that form when atoms gain or lose electrons. These concepts are important in understanding chemical reactions and the behavior of elements in different environments.

Overall, my understanding in atoms is fundamental in science and has far-reaching implications in various fields of study. As students progress in their education, they will continue to build upon their knowledge of atoms and delve deeper into the intricacies of atomic structure. By grasping the concepts of atoms at the eighth-grade level, students lay the foundation for a deeper understanding of the world aro

The structure of an atom is a fundamental concept in the field of chemistry and physics. It provides the foundation for understanding the properties and behaviors of matter. In this essay, we will explore the structure of an atom and its components in detail.

At the center of an atom lies the nucleus, which is composed of positively charged protons and uncharged neutrons. Protons carry a positive electrical charge, while neutrons have no charge. The number of protons in an atom determines its atomic number and defines its identity as a specific element. For example, an atom with one proton is hydrogen, while an atom with six protons is carbon.

Surrounding the nucleus are negatively charged electrons, which orbit the nucleus in specific energy levels or electron shells. Electrons are much smaller and lighter than protons and neutrons. Each electron shell can hold a certain number of electrons. The innermost shell, known as the first shell or K-shell, can hold a maximum of two electrons. The second shell, or L-shell, can hold up to eight electrons, and so on.

In the vast realm of science, few concepts hold the mystique and fascination as the structure of an atom. As I delve into this intricate subject, my understanding has been enriched, unveiling a cosmos within the confines of minuscule particles.

I understand that at the heart of an atom lies its nucleus, a dense core where protons and neutrons reside in a delicate balance of forces. This nucleus, akin to a bustling city, dictates the atom's properties and behavior.

I realized that surrounding this nucleus are electrons, whirling in orbits like planets around a sun. Their movement is governed by quantum mechanics, a realm where probabilities and uncertainties intertwine, adding a layer of complexity to the atom's architecture.

I wish to ask my teacher about the forces that bind these particles together within the nucleus. What mystical glue holds protons and neutrons in such close proximity, defying the natural repulsion of like charges?

Furthermore, my curiosity extends to the behavior of electrons within their orbitals. How do they transition between energy levels, emitting or absorbing photons in the process? And what determines the specific arrangement of electrons in an atom, giving rise to its unique chemical properties?

As I navigate through the intricacies of atomic structure, I am mesmerized by the elegance and orderliness hidden within the microscopic world. Each discovery unveils a new layer of understanding, enriching my perspective on the fundamental building blocks of matter.

In conclusion, my journey into the structure of an atom has been a captivating odyssey, filled with moments of revelation and wonder. Through continuous exploration and inquiry, I aim to unravel the mysteries that lie at the core of our universe, forging a deeper connection with the marvels of nature.

My understanding of the atomic structure is a combination of historical scientific theories and modern quantum physics.

The atom, as I understand it, is composed of three primary particles: protons, neutrons, and electrons. The core, or nucleus, of the atom contains the protons and neutrons. Protons carry a positive electrical charge, while neutrons are neutral, carrying no charge. The number of protons in an atom determines the atomic number, which in turn identifies the element the atom represents.

Surrounding the nucleus, in a cloud-like formation, are the electrons. These particles carry a negative charge and exist in different energy levels, or shells, around the nucleus. The distribution of these electrons in their respective shells determines the chemical behavior of the atom.

The Rutherford's gold foil experiment was a significant milestone that shaped my understanding of the atomic structure. The experiment revealed that an atom is mostly empty space, with a tiny, densely packed nucleus at the center. This understanding contradicted the earlier "plum pudding" model that proposed atoms were a uniform blend of positive and negative charges.

The atom, the smallest unit of matter that retains the properties of an element, is a fundamental concept in the field of science. Understanding its structure provides us with a fundamental understanding of how matter interacts and exists in our universe. The atom is composed of three primary particles: protons, neutrons, and electrons. These particles are distributed in two main areas: the nucleus and the electron cloud. The nucleus, located at the center of the atom, Protons carry a positive charge, while neutrons have no charge. These particles contribute to the atom's mass and determine the atomic number and atomic mass, respectively. The number of protons in an atom also identifies the element it represents on the periodic table. In conclusion, the structure of atoms and the interactions between protons, neutrons, and electrons form the foundation of our understanding of matter.

In this particular lesson, I learned about the Arrangement of Elements in the periodic table. The elements are arranged in groups and periods. I also found out more about metals. They are located on the left side of the periodic staircase on the periodic table and takes up most of the elements on the periodic table. Metals are malleable, ductile, good conductors of heat in electricity, solid at room temperature (except Mercury), and they have a high luster (they are shiny). On the other hand, Non-metals are located at the right side of the periodic table while metalloids are found in the zigzag/staircase part of the periodic table. I also learned that Noble gases are stable while Halogens and Alkali metals react aggressively based from the video my teacher presented.

I realized that there are periodic trends such as atomic radius, metallic property, electronegativity, ionization energy and electron affinity. Atomic radius increases when going down and left same as metallic property. Meanwhile, electronegativity, ionization energy and electron affinity increases when going up and right so in conclusion, the higher the ionization energy the lower the metallic property is in an element.

I have no other questions to ask my teacher but I do wish to learn more in the future.
