Pb2O3
Lead (II) Oxide is the IUPAC name for PbO.
If a number is very large or very small then having a long string of 0s is likely to lead to errors.
Lead Monoxide
The compound described as Pb0 does not exist in isolation. It seems that it is a notation error. The correct notation for lead is Pb with a 0 subscript indicates an oxidation state of 0, but lead typically forms compounds with positive oxidation states.
Lead and oxygen combine to form lead oxide (PbO).
Lead oxide
Advances in science that led to very large and very small numbers.
Lead oxide is composed of lead (Pb) and oxygen (O) atoms. Depending on the oxidation state of lead, lead oxide can exist in different forms such as lead(II) oxide (PbO) and lead(IV) oxide (PbO2). Lead(II) oxide is a yellow solid while lead(IV) oxide is a dark brown solid.
Lead (IV) ion
Lead has Three type of oxides: Lead(II) Oxide = PbO (Generally referred) Lead(IV) Oxide = PbO2 Lead(II,IV) Oxide = Pb3O4
Lead RED (pigment used to produce a "RED" used in ancient JAPANESE gravures.)
Lead oxide is typically made by heating lead metal in the presence of oxygen. This causes a chemical reaction that results in the formation of lead oxide. Lead oxide can also be produced by dissolving lead metal in nitric acid and then drying the resulting solution.
