The electronic configuration of Gd^(2...

The electronic configuration of `Gd^(2+)`is :

A

`[Xe] 4f^(7)`

B

`[Xe] 4f^(7) 5d^(1) `

C

`[Xe] 4f^(8)`

D

`[Xe] 4f^(7) 5d^(1) 6s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
The E.C. of Gd (Z=64) = [Xe] `4f^(7) 5d^(1) 6s^(2)`
`:. `E. C . Of `Gd^(2+) = [ Xe] 4f^(7) 5d^(1)`
Thus option ( b) is correct.
