Oxide - Wikipedia

2019-4-23 · An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygen atom and one other element[1] in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2– atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth''s crust consists of solid oxides, the result of
