Lead - Howling Pixel

Lead is a relatively unreactive post-transition metal.Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter meers of the carbon group.Exceptions are mostly limited to organolead compounds.
