Inert pair are the pairs of electrons present in the outermost shell of atom that do not take part in chemical bond formation because the nuclear charge of such atoms are so high that they don't allow some of the outermost electrons to take part in bond formation.
Further it is mainly found in Sn and Pb having outermost electronic configuration ns^2 np ^2 , in this case as expected that all the electrons should take part in bond formation and they should show a covalency of 4 but due to inert pair effect they can only lose 2 electrons of p orbital.
