Energy Levels of Electrons. As you may remember from chemistry, an atom consists of electrons orbiting around a nucleus. ... They are restricted to orbits with only certain energies. Electrons can jump from one energy level to another, but they can never have orbits with energies other than the allowed energy levels.
The evidence that support Bohr's claim is that electron can only emit light when its energy level changes.
Bohr proposed an atomic model in which;
- the electrons found in an atom can only occupy orbits for which the angular momentum is quantized, which results in discrete values of energy level.
- the electrons in such stationary state or ground state emits no light,
- if an electron jumps to a lower state, it emits a photon whose energy equals the difference in energy between the two states.
Thus, we can conclude that the evidence that support Bohr's claim is that electron can only emit light when its energy level changes.
