An ion is a charged Atom or molecule. The ion is charged because the number of Electrons do not equal the number of Protons in the atom or molecule. If the atom or molecule contains an excess of electrons it will be negatively charged (e.g. OH-) where as if it is depleted in electrons it will have a net positive charge (e.g. H+).
