Define Atomic Size:
Atomic Size
This is half the distance between the middle of two atoms just touching each other. Atomic
radius decreases moving left to right across a period and increases moving down a group.
Explanation:
Increases from top to bottom because we are adding energy levels at each individual period.
Atoms with a smalller nucleus have a larger atomic size becuase they have less of a charge
thus the electrons are farther spread out.
