The magnetic moment is associated with its spin angular momentum and orbital angular momentum. Spin only magnetic moment value of `Cr^(3+)` ion is

A

`2.87 BM`

B

`3.87 BM`

C

`3.47 BM`

D

`3.57 BM`

Text Solution

Verified by Experts

The correct Answer is:
B
The magnetic moment is associated with its spin angular momentum and orbital angular momentum. Spin only magnetic moment value of `Cr^(3+)` ions is `3d^(3)`
Hence magnetic moment `(mu) = sqrt(n(n+2)) BM`
`= 3.87 BM`
