Hydrogen atom Bohr model has Discrete energy levels ;why not mass levels?

Question

Math wise Energy level structure of atoms can be described as discrete mass level as well. If that is the case than the electron mass radiates energy in terms of mass,Isnt that true?
So why did he state that the electron mass as a constant?
Isnt that why his model failed with more complicated atomic structures?

Answer 1

Looking at the electron orbitals in terms of mass would be much too cumbersome and transparent. The fact that Bohr could find such a simple model relating energy to radius is the real triumph.

Answer 2

I'm not exactly sure if I understand what you are saying. The rest mass of an electron is constant. It is .511 MeV. The electron does not have enough kinetic energy in its orbitals to justify relativistic correction to mass.

So what I think are asking why we don't consider gravity when we figure energy levels of bound electrons. And this because the force of gravity acting on the electron is much smaller than the electrostatic force. If we add gravitational affects the answers you calculate will not change.

The Bohr models fails because for two reasons. The first is that when you start adding more than 1 electron, the system gets to complex to calculate exact values. The second is that the Bohr atom is still effectively a pseudo-classical model. You have to solve the wave equation to find the true electron distribution and energy levels.

Answer 3

because how far is the electron depends on its energy not on its mass
