Magnetic Moment
- The magnetic moment of an ion is related to the number of unpaired electrons present in the ion.
- It can be calculated using the formula:
μ = √(n(n+2)) BM
- Where μ is the magnetic moment and n is the number of unpaired electrons.
EXPLANATION:
Ion | Electronic Configuration | Number of Unpaired Electrons | Magnetic Moment (BM) |
---|---|---|---|
Mn2+ | [Ar] 3d5 | 5 | √35 |
Fe2+ | [Ar] 3d6 | 4 | √24 |
Ti2+ | [Ar] 3d2 | 2 | √8 |
Cr2+ | [Ar] 3d4 | 4 | √24 |
Therefore, the ion with the maximum magnetic moment is Mn2+.
