Inorganic compounds can be formally defined with reference to what they are not—organic compounds. Organic compounds are those which contain carbon, although some carbon-containing compounds are traditionally considered inorganic. When considering inorganic chemistry and life, it is useful to recall that many species in nature are not compounds per se but are ions. Sodium, chloride, and phosphate ions are essential for life, as are some inorganic molecules such as carbonic acid, nitrogen, carbon dioxide, water and oxygen. Aside from these simple ions and molecules, virtually all species covered by bioinorganic chemistry contain carbon and can be considered organic or organometallic.
