<onlyinclude>An '''electron volt''' (also written '''electron-volt''' and '''eV''') is a unit of [[energy]], specifically the energy that it takes to move an [[electron]] through the [[voltage|potential difference]] of 1 [[volt]] (or a [[proton]] moving through the same potential difference, in a different direction).</onlyinclude><ref>Jean Tate. (February 17, 2010). ''The Electronvolt'' [Online]. Available: http://www.universetoday.com/56463/electron-volt/ [February 20, 2015]. </ref> This small unit of energy is useful when discussing the energy released from [[chemical reaction]]s or moving electrons closer or further from the [[nucleus]] in an [[atom]].

When converting from [[mass]] to energy the MeV ([[prefixes|mega]] electron volt) is useful. This leads to a derived unit of mass the MeV/c<sup>2</sup>, which is useful for looking at [[nuclear fission|nuclear reaction]]s.
