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

A

0

B

1.73

C

2.84

D

4.9

Text Solution

Verified by Experts

The correct Answer is:
C
`""_(28)Ni^(2+)`:[Ar]`3d^(8)` It has two unpaired electrons.
`mu_(80) = sqrt(n(n+2)) = sqrt(2(2+2)) = 2.828` M
