WebWhy does Pb exist as an ion with +2 valance? The preference of P b for the lower oxidation state is an example for the so-called inert pair effect. Due to relativistic contraction of the outermost s orbital, its 2 electrons are closer to the nucleus and thus more tightly bound than the electrons in the p orbitals.
