A) I remember seeing a video on the way how atoms were drawn on YouTube and referred to that video. The protons and neutrons were tight together and in the center of the nucleus. The electrons surround the nucleus and there are separate shells for each level. Specifically for nitrogen, the first level has 2 electrons and 5 on the next level.

B) It is a neutral atom.

C) The mass number of the nitrogen atom is 14.0067 amu. According to the periodic table that I used.

# data[].attributes.body
The first thing I thought about was the number of electrons, protons, and neutrons that would be in the atom. Since Hydrogen has a mass of about 1 there is no neutron. and only one proton. The atom is also neutral so the one proton, which is shown in the model by the charge signs next to the parts of the atom. The mass number is 1.008 sine one proton has the mass of 1 amu.

a) When drawing this, I wanted to show the protons and neutrons of the oxygen atom.

b) Oxygen is neutral because it has the same number of protons, neutrons, and electrons.

c) Mass number is 16 because 8 protons + 8 neutrons is 16.

I thought the design is pretty basic, I've seen it before. It is obviously not to scale, as even if we were to scale an atom up to the size of a classroom, the nuclei would be the size of a spec of dust.

It is neutral, as the number of protons and electrons are the same.

The mass of the atom is 14, as the total number of protons and neutrons equals 14, but there aren't 7 of each!

1.) The first thing I thought about when constructing my model was whether or not I was going to make it neutral or charged. This gave me a better idea of how many protons and electrons I should have in my model knowing that when an atom does not have equal protons and electrons within it, it will be charged.

2.) I decided to go with a neutral atom of Helium. You can see that the Helium atom model I constructed is neutral because it has an equal number of protons and electrons (2 positively charged protons and 2 negatively charged electrons).

3.) The average mass number of my Helium atom is 4. Knowing that I can calculate the mass number by adding the amount of protons and neutrons that are present in the atom's nucleus, in my case 2 protons and 2 neutrons, I arrived at a mass number of 4.

# data[].attributes.body
a. When drawing my atom I made sure to place the electrons a distance away from the neutrons and protons to show that they are separate from the nuclei. I also made sure that I include the proper number of electrons, neutrons, and protons.

b. The atom is neutral because it is made up of a equal number of neutrons and protons.

c. The mass number = Protons + Electrons
6+6=12
12 is the mass number

# data[].attributes.body
1)The first thing came to my mind when I construct my element was the amount of protein it’s going to have, so I choose 2 that stands for helium.

2)The Atom in my model is neutral because the number of protons and electrons are equal and we can see that in the model that I drew in which they are balanced.

3)We can find the mass number by adding the protons and neutrons in the atom, in which my model has a mass number of four.

# data[].attributes.body
a) Before constructing my model, I found out the number of protons, neutrons, and electrons. I drew the protons and neutrons together as little circles and labeled the protons with the positive sign: "+". For the electrons, I drew them outside in the outer shells.
b) The atom would be considered
neutral due to containing the same number of electrons and protons.
c) The mass number of the atom is 12.
To determine the number of protons, it would be equivalent to the atomic number, which is 6. To determine the number of neutrons it would be equivalent to the mass number minus the atomic number

# data[].attributes.body
a. I thought about the valence electrons, and also drawing from previous information from high school chemistry that the inner ring only has two electrons, and which leaves the last 4 electrons to be on the second ring.

b. The atom has a neutral charge because there are the same amount of protons and neutrons.

c. The atomic mass of my atom is 12 amu. I figured out this number by looking at the bottom numbers on the periodic table.

# data[].attributes.body
A) When I constructed my model, I thought that Hydrogen was simple enough for everyone to understand how I drew it and that it is used on many occasions.

B) The hydrogen atom has a neutral charge. It is shown in the model because the hydrogen atom has the same number of protons and electrons.

C) The mass number of my atom is 1. I determined the mass number by looking at the periodic table.

# data[].attributes.body
a) First, I had to choose which element I wanted to draw. Then, once chosen, I would sort out my information like how many protons, neutrons, and electrons. Then, I create an image of protons and neutrons within a nuclei and the electrons surrounding this.

b) The atom is neutral. It is shown by showing the given atomic mass, which essentially shows the exact amount of neutrons.

c) The mass number of my atom is 4.003. The mass number consists of protons and neutrons. There are 2 protons and the mass number is 4, so therefore the number of neutrons is 2.

# data[].attributes.body
1) I knew I need a nucleus to contain my protons and neutrons. I also knew I need my electrons to be in distinct shells away from the atom.

2)Neutral - There are no empty valence electron shells.

3) 4 My atomic number was 2 and my mass number was 4. My atomic number told me there were 2 protons and subtracting 2 from 4 I concluded that there are 2 neutrons. I knew 2 electrons as electrons and protons are the same.

# data[].attributes.body
a. My thought about the model was that it was fairly simple. It was going to be a neutral charge therefore the number of protons and electrons were to be the same. And knowing hydrogen has 1 proton we can say it has 1 electron as well.

b. My atom shown in the model has a neutral charge having only one proton and one electron to negate the charge.

c. The mass number for hydrogen is 1.

# data[].attributes.body
a) To draw my model of Beryllium (Be) I thought of a couple things. I sort of combined 2 different thoughts in order to make it. First I thought of the general description of an atom so i drew protons and neutrons in the nucleus and then electrons separately. I usually think of the Bohr model when I think of an atom so I drew 2 rings for the electrons to fit on according to how that model behaves, 2 in the first and then 2 in the second. Finally I thought about the idea of the electron cloud and decided to include that.

b) My atom is neutral as there are an equal amount of protons and electrons. 4-4=0

c)The mass number according to my model would 9. Adding the protons and neutrons, 4 protons + 5 neutrons, gets us a mass number of 9.

# data[].attributes.body
a) When making this model, I had considered how many protons, electrons, and neutrons does the atom have. I also had to consider the atomic number and the charge to help me determine how many protons, electrons, and neutrons.

b) The atom is neutral because of the atom's equal amount of electrons and protons. 1 election and 1 proton

c) Atomic mass = # of protons + # of neutrons
atomic mass = 1 + 0 = 1 amu

# data[].attributes.body
a. When I constructed the Oxygen Atom I thought about the number of protons, neutrons, and electrons it had in total. I wanted to make it clear that the negative signs are electrons, the positive signs are protons, and the ones with no signs on them are neutrons.
b. Oxygen is a neutral element, because there are 8 protons, 8 neutrons, and 8 electrons. They all have the sam amount.
c. The mass number of oxygen is 16. I got this answer by adding the protons and neutrons in the atom. 8 protons plus 8 neutrons equal 16.

# data[].attributes.body
a. When constructing my model I thought about how to properly separate the protons from the neutrons because of the lack of color. I also thought about the placement of the electrons around the nucleus and how to make it clear that it was the atom I was making. When making the atom, I chose to use 5 neutrons to be able to match the average atomic mass of the element.

b. The atom is at a neutral charge. This can be seen because there is the same amount of protons as there are electrons. There are 4 of both protons and electrons.

c. The atomic mass of my element is 9 amu. This can be seen because of the 4 protons and 5 neutrons in the nucleus of the element. Proven by the sum of 4 and 5 equaling 9.

# data[].attributes.body
a. I took into consideration the amount of protons, neutrons, and electrons. I also looked at how many rings of electrons there would be.

b. My element neutral. There is the same amount of protons as there is electrons.

c. The mass number is 16 and I know this due to my eyes observing that number on the periodic table.

# data[].attributes.body
a) I chose the element Nitrogen. My first thoughts were to figure out how many protons are contained in atom, I chose 7 neutrons because it directly fits with the average atomic mass. I know the number of electrons is directly correlated with the amount of protons so that's how I ended up with 7 electrons. 2 in the inner orbital, 5 in the outer orbitals. Now that I established what forms nitrogen, I then modeled the picture referencing the Bohr Model of the atom. The nucleus is made up of protons and neutrons and the electrons orbit it.

b) The model I drew does not have a charge. It is shown with 5 valance electrons. Nitrogen is known to react with other nitrogen atoms to form N2 with no additional charges

c) The mass number is 14 here since I took the mass number and subtracted the protons to gain what neutrons I have an rounded down. 14 (total mass) - 7 protons = 7 neutrons

# data[].attributes.body
a: When constructing this model, I thought about how I should create the different places that I should place the protons, neutrons, and electrons in. The protons and neutrons are together in the nucleus, while the electrons orbit around it.

b. The atom has a neutral charge as there is an equal amount of protons to electrons.

c. The exact atomic mass of lithium is 6.941, but it is around 7 when rounded up. There are four neutrons and three protons in the model, which add up to seven.

# data[].attributes.body
1. To construct my model, I had to determine how many protons and electrons there would need to be drawn from the selected element from the list, in this case I chose H.

2. My atom is drawn to be a neutral atom since there is an equal amount of electrons and protons.

3. The mass number of my atom is 1. This was determined by the single proton and no neutrons in the atom.

# data[].attributes.body
Attached is my Image of a Carbon-12 atom that has a -4 charge.

1 a) I considered the fact that the sum of protons and neutrons in a Carbon-12 atom was 12, based on its mass number. Based on its atomic number, 6, I knew that it had 6 protons, and therefore 12-6=6 neutrons. Therefore I drew 6 protons and 6 neutrons within the middle of the atom, indicating they are all located in the nucleus. I intended to draw protons and neutrons of a similar size, since they have the same mass. Secondly, since the electrons are located in mostly empty, outer shells, I drew them as such, outside of the nucleus. The first shell was filled with 2 electrons, while the outer one is filled with 8 electrons. Originally a neutral Carbon-12 atom would have 6 electrons, equal to its protons, but here the C4- ion is shown with 10 electrons as it has drawn 4 electrons from another atom. The innermost shell of an atom can hold 2 electrons, whereas subsequent outer shells can each hold up to 8 electrons.

1b) Here in this atom, there are 4 more than the number of electrons a carbon atom is supposed to have, therefore the -4 charge. I believe that the drawing may not reflect the fact that the C atom bonds covalently instead of ionically with other atoms, therefore it shares electrons with another atom to reach a full shell of 8 electrons, as opposed to the drawing which shows that it has gained 4 electrons.

1c) The mass number of my atom is 12. This is because it has 6 neutrons and 6 protons, and upon adding them together I get a mass number of 12.

# data[].attributes.body
a. When constructing my model, I thought about what the atomic number was and the charge in order to determine the number of protons, electrons, and neutrons I would have to draw.

b. The atom is neutral because there is an equal number of protons and electrons.

c. The mass number of my atom is 4. (2 protons + 2 neutrons)

# data[].attributes.body
A What I thought of when I was drawing this atom was how many protons and electrons this element has.  For this atom I knew that it did not contain any neutrons so I made sure not to put them into the nucleus.
B The atom I have chosen was a neutral atom because it has one proton and one electron so they equal each other out.  This was shown in the drawing by having one proton in the nucleus and one electron orbiting it.  These two together prove to be a neutral atom.
C The mass number of my atom was 1 atomic mass because there is one proton and one electron.  THe reason that it is not higher is because there is no neutrons.

# data[].attributes.body
a. To construct my atom I thought about how many electrons, protrons, and neutrons my element has.
b. From there I decided to give my element a neutral charge, which is shown with there only being one electron and one proton.
c. The mass number of my element is One amu, as it only has one protron, and no neutrons.

# data[].attributes.body
I wanted to make the picture clear showing the proton in the middle and the neutron on the first ring

It is a neutral charge, i state with positive and negatives

The mass is 1, as it has 1 neutron/proton

# data[].attributes.body
a.  I drew a Hydrogen isotope more commonly referred to as tritium.  Which has 2 neutrons, causing it to be a radioactive element. Might be my favorite atom.

b. It has a charge of -1, as can be seen by having 2 electrons, and only one proton.

c. The mass number is 3, which I determined by adding the number of protons to the number of neutrons.

# data[].attributes.body
In constructing my model, I took into account the nucleus containing the neutrons and protons, as well as the outside carrying the electrons. I also took into account the different isotopes of my atom, and what charge I wanted it to have.

The atom has a negative charge, shown by the addition 2 electrons in the image.

The mass number of my atom is approximately  6, as it contains 3 neutrons and 3 protons.

# data[].attributes.body
Step 1:

a. The things I thought of first is how many neutrons, protons and electrons does it have? After that I had to consider the valence shells I needed based on how many electrons there were.

b. The atom is neutral since it contains both 8 neutrons and 8 protons.

c. The mass number of Oxygen is 16 and that is from adding the of protons and neutrons.

# data[].attributes.body
A. I had to think of how many electrons and protons were in one atom of hydrogen and then had to figure out the mass and charge of it.

B. The atom of a hydrogen has a neutral charge, since their is one proton and electron to balance out each other. In the drawing it shows one electron( negative charge) and one proton(positive charge), and from there you can see that it would mean a hydrogen has a neutral charge.

C. The mass of a hydrogen atom is 1, since it is the number of neutrons and protons combined.

# data[].attributes.body
1. before I decided to draw my model of nitrogen I thought about how many protons, neutrons, and electrons it has. I also was thinking about whether to leave it neutral or add a charge.

2. The atom of nitrogen is neutral. It is shown in the model by how all the protons, electrons, and neutrons are all equal.

3. The mass of my atom is 14 and I found this by adding the number of protons to neutrons.

What I thought about as I constructed the model was the amount of protons and electrons make this an equal charge and the atomic number which determined how man

# data[].attributes.body
a) When constructing this model was that since the element, Helium, is atomic number 2, I believe that it would be pretty small since it only has 2 electrons, 2 protons, and 2 neutrons.

b) The charge of the atom is neutral since every protons, neutrons, and electrons are all balanced.

c) The mass number of the atom would be 4 because since you add the total protons and the total neutrons.

# data[].attributes.body
A. The main thing I thought about before drawing this atom was the atomic number of Helium which is 2. That's why I have drawn 2 protons on the inside, and the 2 electrons on the outside to go with it.

B. The atom that I have drawn happens to be neutral. Helium is normally an atom with 2 protons, so to make it neutral I left it with the 2 electrons in its valence.

C. The mass number of an atom is determined by the sum of the protons and the neutrons in the nucleus. The mass number of my Helium atom is 4. You can find this by adding the 2 protons and the 2 neutrons in the nucleus.(2+2=4)

# data[].attributes.body
a. When constructing this model I thought about the atomic number which is the amount of proton and electrons the atom would have and the atomic mass would be the total amount of mass of protons and neutrons.

b. The atom above is neutral because in the picture it shows the same amount of proton to elections.

c. The mass number of my atom is 9 because it is based on the protons and neutrons in the atom.

# data[].attributes.body
a. I thought about what I should draw, such as how many circles and dots. I drew the atom in the orbit form. I pictured in my mind how many protons and neutrons I need to draw by looking at the element in the periodic table. I thought about making the atom neutral by having the same number of protons and electrons.

b. The atom I drew is neutral because there are 4 electrons to match up with the 4 protons.

c. The mass number of the atom I drew is 8 because mass number of the element is made up of 4 protons and 4 neutrons.

# data[].attributes.body
a)For the construction of my model, I thought about drawing a nucleus which contains both protons and neutrons. Being that its a carbon atom, I knew I had to draw 6 protons and 6 neutrons in the nucleus.
b) This atom has a neutral charge because the number of protons equals the number of electrons which they cancel each other out.
c)The mass number of my atom is 12. I determined this by adding up the number of protons and the number of neutrons in my nucleus.

# data[].attributes.body
1) For the construction of my model and I had to think about how many protons, neutrons, and electrons I was going to have in order to make the Helium atom accurate.

2) This atom is neutral because this atom has  the same amount of protons than it has neutrons which makes it have no charge. This is shown in the model by having 2 electrons on the outside and 2 protons in the inside.

3) The mass number of my atom is 4 and this can be found by adding the amount of protons and the amount of neutrons in the atom.

# data[].attributes.body
a) Before constructing my model, things that I thought about were how many protons, neutrons and electrons that I would need. I chose to construct a helium atom, which has an atomic number of 2. This means that in the nucleus, there would be 2 protons and 2 neutrons. Since it is neutral, there would be 2 electrons.

b) This atom is neutral due to the number of protons and electrons being equal, therefore balancing each other out.

c) The mass number of my atom is 4, this is because there are 2 protons and electrons. The electrons' mass is so small that it is negligible.

# data[].attributes.body
a. I thought about how to show the nucleus, and the charges of protons and electrons. I also had to consider spacing and scaling of the particles.

b. The atom has a charge, it's shown by the excess amount of electrons.

c. The mass number is 15, this can be determined by summing up the number of particles in the nucleus.

# data[].attributes.body
I wanted to show some scale not a perfect one but at least some to show how big the protons are compared to the electrons. Atom is neutrally charged as there are only two charges in my model one positive one negative. The mass number to my atom is 1 since I added the # of protons and # of neutrons together. 1+0=1

# data[].attributes.body
a) My thoughts when I was about to construct the model was which of these element would be the easiest to draw.

b) The atom is neutral as shown in the model by having the same number of protons and neutrons.

c) The atomic mass of H is 1. We can determine the mass number by adding up all the protons and neutrons the atom have. In this case, there is only 1 proton which give hydrogen the mass of 1.

# data[].attributes.body
a) Some of the things I needed to think about when constructing this model are the number of protons, the number of neutrons, and the number of electrons.

b) This atom is neutral, so it does not have a charge. In the model, it shows that there are an equal number of protons and electrons (2 each), so there is no charge.

c) The mass number is 4. I got this number because mass number is equal to the number of protons and neutrons. There are 2 protons and 2 neutrons, so it adds up to 4.

# data[].attributes.body
A) To construct the model I thought about having the correct number of protons and electrons for the specific atom and neutrons for the atom that made sense for the element. Also I thought of how atoms are mostly empty space so that is how I drew it.

B) The atom in this picture is neutral and this is shown in the picture in how there are 6 protons and 6 electrons which balance out to have a neutral charge.

C) The mass number of the atom is 12 because is you add the 6 protons with the 6 neutrons you get 12 to be your mass number.

# data[].attributes.body
A. Before drawing the model, I thought about how many fundamental particles (protons, neutrons, electrons) make up the hydrogen-2 atom.

B. This atom is neutral because there are the same number of protons as there are electrons. This can be seen in the model and can be determined by counting the number of protons and electrons.

C. The mass number of this atom is 2 because there are exactly 1 proton and 1 neutron that make up the majority of its mass. While there is an electron in the atom, its mass is so small that in general it is not included in the atomic mass.

# data[].attributes.body
a) I thought that in the nucleus there must be the neutrons and protons and around the nucleus should be the electrons. Because the atomic numbers is 2, that means that there are two protons in the nucleus and because the mass number is 4 (4-2=2) so there must be two neutrons. Because my molecule is neutral there are two electrons to valance the two positive chrges from the protons.

b) The atom is neutral because there are the same amount of protons and electron so their charges balance eachother.

c) The mass number is 4, because there are two protons and two neutrons (the electrons’ mass is considered 0 because it is really small, really close to 0).

# data[].attributes.body
a) In constructing my model, I basically just thought about the three most important things which are protons neutrons and electrons. I decided to go with the most common version of nitrogen so there ended up being seven of each. I then color coded each part, made a key and wrote down the charge and atomic mass and number just for reference.

b) The atom is neutral. In my model I show this in two ways. You can simply look at the writing at the bottom which states there is no charge or look at the diagram and infer that since there’s an equal number of protons and electrons, the atom has no charge.

c) Though the periodic table states that Nitrogen has an atomic mass of 14.007, this is only an average. Since I had the isotope of Nitrogen with equal protons and neutrons, the Atomic mass ends up being 14.

# data[].attributes.body
A. When drawing the atom, I had thought about and considered things like how many of each of the subatomic particles there would be in the atom I was drawing as well as where I would position them, because there are certain rules like protons can't touch each other and how many electrons would be in each shell/energy level of the atom I was drawing.

B. The atom I drew has a neutral charge, because I had drawn three proton and three electrons so the charges cancel out and become neutral.

C. The mass number of the atom I drew is approximately seven, and I figured this out by looking at my periodic table of elements.

# data[].attributes.body
As i was constructing my model, i was thinking about how Helium only has one ring and how relatively simple it is. Because it only has two electrons, would the first ring be considered valence electrons or would only a second ring be considered valence elcectrons.

B) It is neutral because it has same number of electrons as it does protons.

C)It has a mass of four because its nucleus has two protons and two neutrons, making it four.
