the dual nature of the electron.
the uncertainty principle.
finding the suitable equation which describes the wave motion of the electron
all of the previous.
The maximum number of electrons that saturates the principal energy level (n) is given from the rule
2n
n2
2n2
(2n)2
hen (n = 3) and (l = 2). So, electron is located in the sublevel

3d
3f
The possible values of n and l for the same electron are-----
0,1.5
3,3
0,1
2,1
The energy sublevels that form the third energy level are
s
s,p
s,p,d
