Atoms more complicated than hydrogen hav...

Atoms more complicated than hydrogen have more than one proton in their nucleus. Let Z stands for the number of protons in a nucleus. Also imagine that an atom loses all but one of its electrons so that it changes into a positively charged ion with just one electron. Bohr.s formula for the energy levels of the hydrogen atom can easily be changed to apply to such ions. It becomes `E_m = (-Z^2 e^4 m_e)/(8 epsi_0^2 h^2 n^2)`, where m= mass of electron , e= change of electron, n = orbit number.
