Bohr Model Assumptions

• Electrons bound in an atom can only occupy orbits for which the angular momentum is quantized.  This results in discrete values for the radius and energy.

• An electron in such a stationary state emits no radiation.

• If an electron jumps to a lower state, it emits a photon whose energy equals the difference in energy between the two states.

• The angular momentum L of atomic electrons is quantized by the rule L = n h/2p.
