The number of d-electrons retained in Fe...

The number of d-electrons retained in `Fe^(2+)` (At. No Fe=26) ions are:

A

3

B

4

C

5

D

6

Text Solution

Verified by Experts

The correct Answer is:
D
`Fe(z =26) , 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 4s^(2) 3d^(6)`
`Fe^(2+) : 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3d^(6)`
`:.` Number of d-electrons retained = 6
