Among the following series of transition metal ions the one where all meal ions have `3d^2` electronic configuration is

A

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

B

`Ti^(o+),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(Z=22)=3d^24s^2,Ti^(3+)=3d^2`
`V(Z=33)=3d^34s^2,V^(3+))=3d^2`
`Cr(Z=24)=3d^64s^1,Cr^(4+)=3d^2`
`Mn(Z=25)=3d^54s^2,M^(5+)=3d^2`
