Question
Explain giving reason :
Transition metals and many of their compounds show paramagnetic behaviour.
✓

Answer

Transition metals and most of their compounds are paramagnetic, because in them unpaired electrons are found near the metal and those elements or compounds which have unpaired electrons are paramagnetic. Like Sc = [Ar]  3d1  4s2 it has one unpaired electron hence it is paramagnetic, similarly in FeSO4, Fe+2 has four unpaired electrons so it is also paramagnetic.
