Chemical Properties Non Metals
Form anions and cations
Quantum Numbers
S - spin (s)
P - principal (n)
A - angular (l)
M - magnetic (m)
S
e- spin
+- 1/2
P
Distance between e- and nucleus
1 -> 7
A
Orbital’s shape
1 -> 3
s, p, d, f
M
Orbital’s direction
x, y, z
Paramagnetic
e- on VS unpaired, attracted magnets
Diamagnetic
e- on VS on pairs, not attracted by magnets
Metals
Never receive e-, only form cations
Alkaly Metals

Highly reactive with water and oxygen
Alkaline Metals
Less reactive
Appear as oxides in nature
Halogens
Diatomic molecules
