Introduction to Quantum Physics
... The electron moves at circular orbits around the proton under the influence of the Coloumb force of attraction. Only certain electron orbits are stable. These stable orbits are the ones in which the electron does not emit energy in the form of radiation. Radiation is emitted by the atom when the ele ...
