As we learnt
Periodicity of valence or oxidation states -
The oxidation state of an element in a particular compound can be defined as the charge acquired by its atom on the basis of electronegativity consideration from other atoms in the molecule.
-
Due to inert pair effect +2 oxidation state of Pb is most stable.
