Why transition elements show variable oxidation state and generally exhibit paramagnetic behaviour?
Answers

The paramagnetic behavior increases as the number of unpaired electron increases. ... Variable oxidation state is due to the participation of outer ns and penultimate (n-1)d electrons in bonding since these orbitals have almost equal energies. · The most common oxidation state shown by 3d series is +2.
