The expected spin magnetic moment of Fe...

The expected spin magnetic moment of `Fe^(3+)` is :

A

4

B

7

C

5

D

6

Text Solution

Verified by Experts

The correct Answer is:
C
`Fe^(2+)` ion electronic configuration is `4s^(0)3d^(6)` and has 4 unpaired electrons.so magnetic moment is
`mu=sqrt(n(n+2))`B.M`=sqrt(4(4+2))=sqrt(24)` `therefore` The magnetic moment of `Fe^(2+)` ion is approximately equal to 5.
