Magnetic moment 2.83 BM is given by which of the following ions - (AT. Nos. Ti = 22, Cr = 24, Mn = 25, Ni = 28)

A

`Ti^(3+)`

B

`Ni^(2+)`

C

`Cr^(3+)`

D

`Mn^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Ti^(3+):3d^(2)4s^(0)` , magnetic moment,
`mu =sqrt(n(+2))=sqrt(2(2+2))=sqrt(8)=2.83 BM`
