[O][=Pb]"}, {"from": "gpt", "value": "The molecule are a group of inorganic compounds with formulas including lead (Pb) and oxygen (O). It occurs in both a red and yellow form. It occurs naturally as the minerals litharge (red form) and massicot (yellow form).  Lead oxide is found in paints and is used extensively in the manufacturing of lead glasses, ceramic glazes, and batteries. Lead is a heavy metal and stable element with the symbol Pb and the atomic number 82, existing in metallic, organic, and inorganic forms. It is mainly found in nature as the mineral galena (PbS), cerussite (PbCO3) or anglesite (PbSO4), usually in ore with zinc, silver, or copper. (L21, L412)"}]
