A) the relationship between orbital radius and energy

D) why electrons in atoms don't radiate all their energy away rapidly

Question

Quizplus · Accepted Answer

The planetary model of the atom failed to explain why electrons in atoms don't radiate all their energy away rapidly, also known as the stability of atoms. This led to the development of the quantum mechanical model of the atom.  The other options are explained by the planetary model or Rutherford's nuclear model.
