Lead shows oxidation states of +2 and +4 in its compounds. Among the many important lead compounds are the oxides: lead monoxide, PbO, in which lead is in the +2 state; lead dioxide, PbO 2, in which lead is in the +4 state; and trilead tetroxide, Pb 3 O 4. Lead monoxide exists in two modifications, litharge and massicot.
