The fact that electrons occupy certain specified energy levels in which they are radiation less solves the problems associated with the Rutherford model.
According to the Bohr-Sommerfeld Model of the atom, the electrons in an atom tend to occupy certain specified energy levels in which they are radiation less.
Recall that following from the Rutherford model and the and the Maxwell's laws, an accelerating charge radiates energy. Thus, the bottle neck is removed by assuming that electrons occupy specific energy levels in which they do not move about an loose energy.
This eliminates the possibility that the electron could spiral into the nucleus.
