Which of the following has more unpiared d-electrons?

A

`Zn^(+)`

B

`Fe^(2+)`

C

`Ni^(3+)`

D

`Cu^(+)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Zn^(+) : 1s^(2) 2s^(2)2p^(6) 3s^(2) 3p^(6) 4s^(1) 3d^(10)`
`Fe^(2+) : 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(6)`
`Ni^(3+) : 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(7)`
`Cu^(+) : 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(10)`
