| Nov 8, 2019 at 12:59 | comment | added | Stefano Borini | Because the hydrogen system is an extremely simple system, and its approximation is just good enough for such system. Even when you introduce modern quantum mechanics, the orbitals are still described in terms of the eigenvalues of the only system we can solve analytically: the hydrogen atom. | |

| Nov 6, 2019 at 17:28 | comment | added | Stefan | I also heard that there should be some deep result in QM that could explain why bohr succeeded, but I failed to find it. | |
| Nov 6, 2019 at 17:25 | comment | added | Andrew Steane | The Bohr model is a combination of some correct physics (Coulomb's law, kinetic energy, angular momentum), empirical input (the hydrogen emission spectrum), and some conjectures about quantisation. I would say the degree of correctness at matching the energy levels is a combination of luck and judgement. | |
| Nov 6, 2019 at 17:23 | comment | added | jacob1729 | That it predicts the energy scale of an atom correctly is a lucky coincidence helped out by the fact there is only one energy scale in atomic physics (the one defined by $h,\epsilon_0,e$). That it predicts the correct $-1/n^2$ dependence is more impressive. | |
| Nov 6, 2019 at 17:18 | comment | added | Stefan | I have studied the Bohr model and I doubt that it is a result of a tweak, there is too many natural assumptions and natural deductions and to many correct digits in the result. If there was more fudging I would agree with you though. | |

| Nov 6, 2019 at 16:14 | comment | added | Manvendra Somvanshi | The energy eigen values as predicted by Schrodingers equation is the same as Bohr's prediction. Since Schrodingers equation is a non relativistic and spinless approximation of the Dirac equation, Bohr's model can be thought of as the approximation of an approximation of Dirac equation. | |
| Nov 6, 2019 at 16:11 | comment | added | verdelite | I would say Bohr designed his theory to predict the then-known phenomenons. That is why. | |
