Explain giving reasons :
Transition metals and many of their compounds show paramagnetic behaviour.

Text Solution

Verified by Experts

Transition elements have unpaired electrons. Each unpaired electron has a magnetic moment associated with its spin angular momentum and orbital angular momentum. This is the reason of paramagnetism in transition metals.
