The expression for the energy of an electron is:

$\overline{){{\mathbf{E}}}_{{\mathbf{n}}}{\mathbf{=}}\mathbf{\left(}\mathbf{-}\mathbf{2}\mathbf{.}\mathbf{18}\mathbf{×}\mathbf{10}\mathbf{-}\mathbf{18}\mathbf{\right)}{{\mathbf{Z}}}^{{\mathbf{2}}}\mathbf{\left[}\frac{\mathbf{1}}{{\mathbf{n}}^{\mathbf{2}}}\mathbf{\right]}}$
