Among the following series of transition metal 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^(2+),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
`._(22)Ti=3d^(2)4s^(2),Ti^(2+)=3d^(2)" : "._(23)V=3d^(3)4s^(2),V^(3+)=3d^(2)`
`._(24)Cr=3d^(5)4s^(1),Cr^(4+)=3d^(2)" : "._(25)Mn=3d^(5)4s^(2),Mn^(5+)=3d^(2)`.
