Is me again the greatest doctor Sho! Becuase I am the best, so I deside to teach you guys more. Let's talk about Atomic Size this time. Oh yeah~
The size of atomic which is the distance from outer shell to the nuleus. That's easy to understand right~
The formula for Atomic Size actually was same with circle area formu;a.
It is different with Ionilation Energy. So, in the Periodic Table of the Elements, the group and period are also different. For the period it will become decrease this time and from left to right. For the group it will become increase from top to bottom.
For the period, the reason that it become decrease is because the protons number, which means more protons will pull more electrons and the radius become smaller.
For the group, we can use the same examples with elements H and Li, because of the shells number different, so the distance will also different.
Don't thank me! I know I am the best docter in this world! Dr. Sho~
