The electronic configuration of ` ._(46)Pd` is :

A

`4s ^(2) 3d ^(8)`

B

`4s ^(1) 3d ^(9)`

C

`5s^(0) 4d^(10)`

D

`5s^(2) 4d^(8)`

Text Solution

Verified by Experts

The correct Answer is:
C
Palladium is diamagnetic. The configuration `5s^(2)4d^(8)` cannot explain its diamagnetic nature. Pd will be diamagnetic if both the 5eelectrons are transferred to 4d-orbitals.
