Among the following series of transition metals ions, the one where all metal ions have `3d^(2)` electronic configuration is:

A

`Ti^(3+),V^(2+),Cr^(3+),Mn^(4+)`

B

`Ti^(+),V^(4+),Cr^(6+),Mn^(7+)`

C

`Ti^(4+),V^(3+),Cr^(2+),Mn^(3+)`

D

`Ti^(2+),V^(3+),Cr^(4+),Mn^(5+)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Ti_(22)=3d^(2)4s^(2),Ti^(2+)=3d^(2)`
`V_(23)=3d^(3)4s^(2),V^(3+)=3d^(2)`
`Cr_(24)=3d^(4)4s^(2),Cr^(4+)=3d^(2)`
`Mn_(25)=3d^(5)4s^(2),Mn^(5+)=3d^(2)`.
