One unpaired electron causes magnetic moment of 1.1 BM. The magnetic moment of `_(26)Fe^(2+)` is

A

`4.4`

B

`5.5`

C

`2.2`

D

0

Text Solution

Verified by Experts

The correct Answer is:
A
`._(26)Fe^(2+)` has configuration `[Ar] 3d^(6)`. It has 4 unpaired electrons. Thus, magnetic moment is `4 xx 1.1 = 4.4 BM`.
