Magnetic moment 2.84 BM is given by

Answer»

`Cr^(2+)`
`Co^(2+)`
`Ni^(2+)`
`Ti^(3+)`

SOLUTION :`Cr^(2+)-3d^(4):4 "unpaired ELECTRON"`
`Co^(2+)-3d^(7),3:4 "unpaired electron"`
`Ni^(2+)-3d^(8):2"unpaired electron"`
`Ti^(3+)-3d^(1):1"unpaired electron"`
Magnetic moment`(MU)=SQRT(n(n+2))=sqrt(2(2+2))=2.86BM`
It shows that `Ni^(2+)` with 2 unpaired electrons MATCHES the value of magnetic moment.
