In PbO₂ (which is not a valid chemical formula), O and S have an oxidation state of -2. Thus, the sum of the oxidation states of Pb, O and S should be equal to zero. Therefore, Pb's oxidation state can be calculated as follows: (+x) + (-2) + (-2) = 0 x - 4 = 0 x = +4 Thus, the oxidation number of Pb in this compound is +4 or D.
