Can someone help me with representing some quantities without units. I found that in atomic physics atomic units usually aren't used. For example Energy is(adsbygoogle = window.adsbygoogle || []).push({});

[tex]E=\frac{-1}{n^2}[/tex]

Period of classical electron orbital i given by

[tex]T=2 \pi n^3[/tex]

Here n is Principial quantum number. How are derived these formulae??

Thank you
