An oxide is a chemical compound containing at least one oxygen atom and at least one atom of one other element. Most of the Earth's crust consists of oxides^[source?]. Oxides can be made when elements are oxidized by air (when oxygen in the air reacts with the element).

Some common oxides are:

Water (hydrogen oxide) (H₂O)
Iron(III) oxide (Rust) (Fe₂O₃)
Aluminium oxide (Al₂O₃)
Lead(II) oxide (PbO)
Calcium oxide (CaO)
Carbon dioxide (CO₂)
Carbon monoxide (CO)
Magnesium oxide (Magnesia) (MgO)
Phosphorus pentoxide (P₄O₁₀)
Sulfur dioxide (SO₂)
Sulfur trioxide (SO₃)
Silicon dioxide (SiO₂)
Nitrous oxide (laughing gas) (N₂O)
Zinc oxide (ZnO)
Copper(I) oxide (CuO) and Copper(II) oxide (Cu₂O)
