Which of the following metaks has the highest value of exchnage enegry?

A

Zn

B

`Cr`

C

`Cu`

D

`Mn`

Text Solution

Verified by Experts

The correct Answer is:
C
The electronic configuration of `Cu` is `[Ar]3d^(10)4d^(1)`. It has completely filled `3d` subshell which can hev exchanges of electrons pairs as well as of individual electrons resulting in maximum number of exchanges and, hence, maximum exchange energy.
