WebHow is the variability in oxidation states of d-block different from that of the p-block elements? Answer: It is due to similar energy of (n – 1 )d and ns orbitals, electrons from both can be lost. In p-block, lower oxidation state is more stable due to inert pair effect, whereas in ehblock elements higher oxidation states are more stable. Web138 Chemistry-XII 1.
