The spin-only magnetic moment [in units ...

The spin-only magnetic moment [in units of Bohr magneton, `(mu_(B)` of `Ni^(2+))` in aqueous solution would be (atomic number of `Ni=28)`

A

2.84

B

4.9

C

zero

D

1.73

Text Solution

Verified by Experts

The correct Answer is:
A
Configuration of `Ni^(2+)` ion.
[Ar]
No. of unpaired electrons (n)=2
(mB)=`sqrt(n(n+2))=sqrt(2(2+2))=sqrt(8)=2.84`
