Limitations of Rutherford's model of an atom are :
(I) Any charged particle when accelerated is expected to radiate energy. To remain in a circular orbit, the electron would need to undergo acceleration. Therefore, it would radiate energy. Thus, the revolving electron lose energy and finally fall into the nucleus. If this were so, the atom should be highly unstable. Therefore, matter would not exist, but we know matter exists. It means that atoms are quite stable. Thus, it could not explain the stability of an atom when charged electrons are moving under attractive force of positively charged nucleus.
(ll) Rutherford's model could not explain the distribution of electrons in the extra portion of the atom.

The limitations of Rutherford's model of the atom are :-
♥ It was inadequate to explain the stability of an atom .
♥ It did not mention anything about the arrangement of electron in the orbit .
