Question

The magnetic moments of lanthanide ions due to the contribution of ………of their electrons.

Answer 1

Answer:

C 5f electrons in actinides are too diffuse and are less effectively shielded which results in considerable quenching of orbital contribution, and hence the magnetic moments of actinides are significantly less than theoretically predicted values.

Explanation:

Magnetic moments of actinides are significantly less than their theoretically predicted values. This is because electrons of actinides are less effectively shielded which results in quenching of the orbital contribution
