Magnetic moment 2.84B.M. is given by : (...

Magnetic moment `2.84B.M.` is given by : (Atomic numbers. `Ni=28`, `Ti=22`, `Cr=24`, `Co=27`)

A

`Ti^(3+)`

B

`Cr^(2+)`

C

`Co^(2+)`

D

`Ni^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
D
Magnetic moment `(mu)` for `Ni^(2+)=sqrt(n(n+2))`

`n=2`
`mu=sqrt(2(2+2))`
`=2sqrt(2)`
`=2.84` B.M
