diamond and graphite are carbon
A molecule typically does not have electrical [[charge]] (see also [[polyatomic ion]]).
A molecule typically does not have electrical [[charge]] (see also [[polyatomic ion]]).
Most molecules are composed of two or more elements, but they can also be composed of multiple atoms from the same element. Single element, bimolecular molecules which are more commonly known as homonuclear diatomic molecules <ref>http://xbeams.chem.yale.edu/~batista/vvv/node33.html</ref><ref>http://www.chem.purdue.edu/gchelp/gloss/homodiatomic.html</ref> include many elementary [[gas]]es, such as [[oxygen]] (O<sub>2</sub>), [[hydrogen]] (H<sub>2</sub>) and [[fluorine]] (F<sub>2</sub>). Single element compounds also include man-made compounds such as [[buckminsterfullerene]]s, which are "balls" of 60 carbon atoms, as well as natural compounds like [[graphite]], [[diamond]]s, and many [[metal]]s.

Molecules are typically specified by indicating what atoms they are made of and how many of each they possess. If there is more than one of an atom, its count is given by a subscript. Water has two [[hydrogen]] atoms and one [[oxygen]] atom, so it is H<sub>2</sub>O.
