In Bohr model of Hydrogen, the electron will not slowly lose energy as they travel, and hence will remain in stable, non-decaying orbits. Let me ask a "silly" question. Is the electron in Hydrogen ground state stationary or moving? If it is moving, surely it will accelerate and it will radiate according to Maxwell equations? So why Bohr assumption above works? Please tell me why the Maxwell equations do not work any more in the hydrogen atom.
