I learn about what is the meaning of ionization energy , how the trend of ionization energy in the periodic table down the group and across the period and alsothe equation of first second & third ionization energy. I think i need to study more at how to do draw the ionization energy graph.

Reflection/ summary of what i learnt
S, P, & D

The periodic table is divided into 4 blocks

S - Group 1 to Group 2 + helium (1 orbital)

P - Group 13 to Group 18 (3 orbitals)

D - Transition Metals (5 orbitals)

Concept of S, P & D

Lowest energy subshells are filled first

Free radical

A species that has one or more unpaired electrons

Examples of electron configuration

S block - Lithium

1S2 2S1

P block - Phosphorus

1S2 2S2 2P6 3S2 3P3

D block - Cadmium (+shorthand rule)

[Kr] 5S2 4D10

Ionisation Energy

energy required to remove 1 electron from every 1 atom in 1 mole of gaseous ion

Factors affecting ionisation energy

Size of nuclear charge

Distance between outer electron and nucleus

Shielding effect (electrons that are in complete shell)

Ionisation energy in the periodic table

Down the group

Nuclear charge increase

Shielding effect increase

Distance increase

Across the period

Nuclear charge increase

Shielding effect stay the same

Distance decrease

Ionisation energy graphs

that is what i learnt in chapter 1. Improvements i can make, applications of ionization energies because in practice worksheets i still have a hard time understanding.

Within the topic of ionisation energy, I learned several things regarding the property. Ionisation energy is the energy needed to detach an electron from a mole of gaseous atom. Doing it consecutively is called successive ionisation energy. It is affected by nuclear charge, the distance between the shell and the nucleus, and the shielding effect. In regards to the prior topic, I have learned about the principal quantum shells, atomic orbitals, subshells. I also learned how the electrons interact with each other within the orbitals. I have also learned how to write the electronic configurations of the elements that we will be using(except for the lanthanides and actinides).

In this chapter, I've learned how the subatomic particles: proton, neutron, electron, behave in an electric field. I also learned about the electronic structure: principal quantum shells, subshells (s,p,d,f) and atomic orbitals. Furthermore, I learned how to describe the electronic configuration of atoms and ions, as well as writing the full and shorthand electronic configuration. This chapter also taught me all about ionization energy (IE).

However, I still have to improve on explaining the patterns in ionisation energies in the periodic table.

I have learnt about ionisation energy, sub-subshells, atomic orbitals and electronic configurations. I understand about the energy difference between sub-shell 3d & 4s.

But I need to improve on drawing ionisation energy graph.

I have learnt how ionization energy works, and how there are factors that can affect it. I’ve learned about the graph, and how the graph can have a sharp, gradual increase or even a big jump. The higher the group level, the higher the energy, as of its complete shell.

I think i still need to improve on drawing the graph of the ionisation energy

Reflection:
This week i learned in detail about ionisation energies, in elements and the periodic table and what factors affect them. I also learned a bit of stochiometry like formula mass, molecular mass etc. All in all i think i understand the concepts but i just need to practice more with ionisation energy.

1. What have you learned?

Based on the syllabus, I have learned about the atomic structure, deeper into the electronic configuration as well as ionisation energies. Knowing that electron shells have different subshells inside them made me realise that chemistry is now more complex than what we have learned in the past two years and it will be even more complicated in the future ahead.

2. Which part that you need to learn more?

I think that I have to practice more in formulating shortened electronic configurations.

Reflection:

1. I’ve learned a lot of things this chapter, such as the atomic structure of atoms, their charges, relative mass, isotopes and the different extent of deflection each subatomic particle will experience. I’ve also learned that the electron configuration is more complicated than what we’ve learned in IGCSE and there are principal quantum shells, subshells (s, p, d, f) and atomic orbitals. I’ve also learned that there are trends across the period (smaller radius as it goes from left to right) and down the group (larger radius). And there are factors causing that (shielding effect, nuclear charge, distance of valence electrons from nucleus, attraction, etc), as well as the 4 factors that affects the ionisation energy of elements.

2. I probably need to revise more on writing down the electron configuration as there are elements following an exception rule (Such as Copper and Chromium) and revise more about the spin-pair repulsion because elements with spin pair repulsion have lower first ionization energy due to the first electron being easier to be removed.

I learnt about the atomic structure, isotopes, electronic configurations, ionization energy and more. I think I need to study more on how to explain about ionization energy. Such as explaining the trends in the periodic table. I need to also formulate my explanations with more scientific words.
