DRAWBACKS OF THE NUCLEUR MODEL OF AN ATOM :-
▪ The nucleur model of an atom failed to explain how an atom remains stable despite having positive and negative charges present in it.
▪Maxwell has suggested a theory according to which if any charged particles moves in a circular motion it radiates energy.
▪ So, if electrons start moving in, a circular motion around the nucleus they would also radiate some energy which would decrease at the speed of the electrons.
▪ As a result, they would fall into the nucleus because of its high positive charge.

Answer:
The major drawback of Rutherford experiment is that the orbital revolution of the electron is not expected to be stable. According to Rutherford's model, the electrons, while moving in their orbits, would give up energy. This would make them slow down, gradually and move towards the nucleus. The electrons will follow a spiral path and then fall into the nucleus. Ultimately, the atom would collapse. But in reality the atom is stable.
