Atomic Radius
space between outermost shell and nucleus, measure of atomic size
ionization energy
energy it takes to remove outermost electron
electronegativity
the ability attract free electrons/gain electrons, negative ion
if EN inclines, what happens to atom size and IE?
Ie will incline, AR will decline
If EN declines, what about IE and AR
IE declines, AR inclines
when going across a period (horizontal) does AR increase or decrease
decrease due to increase of protons
when going down a group, does AR incline or decline
inclines due to increase of shells
electropositivity
the ability to lose electrons, positive ion
