Hello everyone! I am doctor Sho~ Today let me talk some about what is Ionization Energy!
As the term suggests. Ionization Energy is the energy to pull the electrons. The formula for it is F= K*q1q2/r^2
So! What is Ionization Energy? Good questions！
There have one more things you have to know that how is it change in the Periodic Table of the Elements for groups and period!
For the groups! It will become decrease from top to bottom. and It also will become increase from left to right for the period! Remember it!
For example, in the period. the ablity of element Li to attract electron is one, and the element F is on the right for Li, which means the ability to attract the electron is greater then Li, so it also means the radius of F is smaller, so the nucleus will also near to the element of F.
I guess you still can't understand it, but it's ok because I am a nice teacher!
The other example for group! It is different with period. Like element H only have one shell but element Li have to two shells, which means the radius of Li is bigger than H and longer than nucleus. So, the ability of it will weaker.
So! in summary, here is the definition and rule for Ionization Energy. Don't thank me, I know I am the best!
