Quantum Numbers
Principal QN n pos integers starting at 1 - max =7
Angular Momentum QN l zero to n-1
Magnetic QN m "-l to zero to +l
Spin QN s "+ 1/2 or - 1/2
if n = 1 first energy level
l = 0 s sublevel
m = 0 one orientation
if n = 2 second energy level
l = 0 s sublevel
m = 0 one orientation
l = 1 p sublevel
m = -1 three orientations
m = 0
m = +1
if n = 3 third energy level
l = 0 s sublevel
m = 0 one orientation
l = 1 p sublevel
m = -1 three orientations
m = 0
m = +1
l = 2 d sublevel
m = -2 five orientations
m = -1
m = 0
m = +1
m = +2
