An oxide is a chemical compound containing an oxygen atom and other elements. Most of the Earth's crust consists of oxides. 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)
