The "spin-only" magnetic moment [in units of Bohr magneton, `(mu_B)`] or `Ni^(2+)` in aquenous solution would be :
(At no. `Ni = 28`).

A

1.73

B

2.84

C

4.9

D

0

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `Ni^( 2+)` has two unpaired electrons.
:. `mu = sqrt(n(n +2)) sqrt(8) = 2.84 BM`.
