Organic Chemistry, or the chemistry found in living things, is the chemistry of Carbon; inorganic chemistry is the chemistry of everything else. In general, inorganic compounds are those that contain no carbon. The most ubiquitous of these is the water molecule, (H2O). Other common compounds include ammonia (NH3) and common table salt, Sodium Chloride (NaCl.)
By definition, a compound must be made up of two or more different kinds of atoms, as these prior examples show. Water is a compound as well as a molecule; a molecule may be made up of different kinds of atoms, or may have the same atoms, as in a molecule of Ozone, which is three Oxygen atoms covalently bonded (O3).
