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

1.	Explain the magnetic properties of transition (or d-block) elements.
Answer» Most of the transition metal ions and their compounds are paramagnetic in nature due to the presence of one or more unpaired electrons in their (n – 1)d-orbitals. Hence they are attracted in the magnetic field. As the number of unpaired electrons increases from 1 to 5 in J-orbitals, the paramagnetic character and magnetic moment increase. The transition elements or their ions having all electrons paired are diamagnetic and they are repelled in the magnetic field. Metals like Fe, Co and Ni possess very high paramagnetism and acquire permanent magnetic moment hence they are ferromagnetic.
