Chemical compound where oxygen atoms are combined with atoms of other elements
For negatively-charged polyatomic ion containing oxygen, see Oxyanions.
The unit cell of rutile, an important oxide of titanium. Ti(IV) centers are grey; oxygen centers are red. Notice that oxygen forms three bonds to titanium and titanium forms six bonds to oxygen.
An oxide (/ˈɒksaɪd/) is a chemical compound containing at least one oxygen atom and one other element[1] in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O2– ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials considered pure elements often develop an oxide coating. For example, aluminium foil develops a thin skin of Al2O3 (called a passivation layer) that protects the foil from further oxidation.[2]
