Basic leak in Rutherford's model of atom was that electron would emit energy while orbiting around nucleus and this energy loss would lead to electron's spiraling to the nucleus and collapse of both atom and atom model. Then Niels Bohr came with the idea that electron exists only in discrete orbits, what prevents it from falling. But still, in his model, electron does orbit nucleus and thus radiates energy. My question is - what keeps it standing in the same orbital? How is it possible that electron which stands in ground orbit keeps the energy associated with that orbit if it obviously radiates some energy just by orbiting around?
