Question

Explain the magnetic properties of d-block (or transition) elements.

Answer 1

1. Due to the existence of one or more unpaired electrons in their (n - 1) d orbitals, the majority of transition metal ions and their compounds are paramagnetic. As a result, they are drawn to the magnetic field.
2. The paramagnetic property and magnetic moment rise as the number of unpaired electrons in d orbitals increases from 1 to 5.
3. The diamagnetic transition elements and their ions, which have all of their electrons coupled, are attracted by the magnetic field.
4. Metals like Fe, Co and Ni possess very high paramagnetism and acquire permanent magnetic moment hence they are ferromagnetic.
