The binding energy of a H-atom, considering an electron moving around a fixed nuclei (proton), is \(\rm B = -\frac{me^4}{8n^2\varepsilon^2_0h^2}\). (m = electron mass).
If one decides to work in a frame of reference where the electron is at rest, the proton would be moving arround it. By similar arguments, the binding energy would be
\(\rm B = -\frac{Me^4}{8n^2\varepsilon^2_0h^2}\) (M = proton mass)
This last expression is not correct because
1
n would not be integral.
2
Bohr-quantisation applies only to electron
3
the frame in which the electron is at rest is not inertial.
4
the motion of the proton would not be in circular orbits, even approximately.
