Electron Volt

In atomic and nuclear physics, a commonly used unit of energy is electron volt. An electron volt is the change in the kinetic energy of an electron when it is taken through a potential difference of one volt. Thus,

\begin{eqnarray*} {\rm 1 eV} &=& \mid {\rm charge\ of\ an\ electron}\mid \times ... ...\ }\times 1\ {\rm volt}\\ &=& 1.6\times 10^{-19} \ {\rm Joule} \end{eqnarray*}
