Sc has the following electronic configuration:

(1s)^2(2s)^2(2p)^6(3s)^2(3p)^6(3d)^1(4s)^2. 

Using the elctronic configuration, write down all possible term symbols describing this configuration. Which one is lowest in energy according to Hund's rules?

Step 2

Electronic configuration of Sc is 1s2 2s2 2p6 3s2 3p6 4s2 3d1

S =1/2

2S+1 = [2 x (1/2)] + 1 = 2

The possible l vales for d subshell is +2,+1,0,-1 and -2.

Here only one electron, so l = 2, therefore symbol is D.

 

J value varies from L+S to L-S,

2 + (1/2)  to  2 + (-1/2)

So all possible J values a...
