Question

Give the valance electron configuration for the following atoms and ions. Leave a spaces in between orbitals example: 1s2 2s2 

a. Mn^2+

b. As 

c. S

d. I

e. V+

Expert Solution
Valence Electronic configuration of Mn2+

Atomic no. Of Mn is 25

So, Z for Mn is 25

Electrons in Mn is 25

But Mn is in +2 state , so electrons are 23.

So, outer electronic configuration is 3d5.

 

 

Valence Electronic configuration of As

Atomic no. Of As is 33

So, it has 33 electrons

3d10 4s2 4p3 

Valence Electronic configuration of S

Atomic no. Of S = 16

3s2 3p4
