The "spin-only" magnetic moment [in units of Bohr magneton, (BM)] of Nit in aqueous solution would be (atomic number of Ni = 28)

A

2.84

B

4.9

C

0

D

1.73

Text Solution

Verified by Experts

The correct Answer is:
A
`Ni^(2+)(Z=28):3d^8` number of unpaired electrons = 2
`mu = sqrt(n(n+2)) = sqrt(2(2+2)) = sqrt(8) = 2.84`
