An ion is formed when an atom either loses electron(s) from its outer shell or gains electron(s) so that the outer shell has 8 electrons, thus making it stable. Atoms which lose electrons form positive ions and those which gain electrons form negative ions. Metals form positive ions and non-metals form negative ions.
