The pair of ions having same electronic configuration is__________.

A

`Cr^(3+) , Fe^(3+)`

B

`Fe^(3+), Mn^(2+)`

C

`Fe^(3+), Co^(3+)`

D

`Sc^(3+), Cr^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Cr^(3+) = [Ar]^(18) 3d^(3), Fe^(3+) = [Ar]^(18) 3d^(5), Mn^(2+) = [Ar]^(18) 3d^(5)`
Thus, `Fe^(3+) and Mn^(2+)` have the same electronic configuration
