rutherford’s model

1.while the electrons are moving around the nucleus they'll lose energy constantly. after losing energy, they should fall into the nucleus ultimately. hence atom should collapse, but in reality, this does not happen.
2.he could not explain the spectrum of an atom

bohr’s atomic model postulates

(i) explained the stability of the nucleus by postulating that the electron can
orbit the nucleus in only those special orbits in which it does not radiates energy.
(ii) explained the line spectrum by postulating that the electron emits photons of well defined unique energies when it undergoes a transition from one permitted orbit to another.
