Select the option on which Bohr's model was not based
1.Only certain orbits are stable. In these states, electrons do not emit energy in the form of radiation. 2.Radiation is emitted when electrons make a transition from one energy state to another; the frequency of the emitted photon is related to the change in the atom's energy and independent of the frequency of the electron's orbital motion. 3.Electrons move in circular orbits around the nucleus. 4.Angular momentum is dependent solely on energy, and thus is also quantized.
