Chem Chap 7-8

Electron Affinity
- more negative to the right
- more positive down
ionization energy
- positive left to right
- decreasing going down
(highest in right corner)
atomic radius
- atoms smaller left to right
- larger going down
- (highest at bottom left)
electronegativity
- increases diagnally from lower left to upper right
- (highest in top right)
x=>2.2

nonmetals
x=<1.8

metals
x=2

semimetals
non polar covalent bond=
- atoms attract e- with equal amounts of strength
- (no unit difference)
polar covalent bonds
- e- are unequally attracted
- (less than 2 unit difference)
ionic bond
- sharing of e- so unequal that ions are formed
- (2 units greater or more)
