The transition metal ion that has 'spin -only ' magnetic moment value of 5.96 is

A

`Mn^(2+)`

B

`Fe^(2+)`

C

`V^(2+)`

D

`Cu^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
A
`MN^(2+)` With electronic configuration `3d^(5) 4s^(0)` upaired electrons. Spin -only magnetic moment
` (mu_(s)) = sqrt(4s(s+1)) , S= 5/2 `
` mu_(s) = sqrt(4xx 5/2 (5/2+1))`
= 5.916 = 5.92 BM
