Question

Give drawbacks of Rutherford's model.

Answer 1

The particle move in the atom. The particle while moving would go acceleration and fall into the nucleus. That means atom is unstable but we know that atom is quite stable. Basically, Rutherford didn't able t o explain the stability of the atom.

Answer 2

Hello !!!

Rutherford after his gold foil experiment claimed that electrons move around the nucleus which is positively charged and centrally located. He explained that the force of attraction between the positive and negative charge is balanced by the centrifugal force.

But Maxwell's electromagnetic theory states that if a charged particle moves around another charged particle, it gradually loses energy.

So electron is a charged particle and nucleus is also charged. When electron moves around the nucleus it should gradually lose energy, follow a spiral path and should fall into the nucleus. But this does not happen. Rutherford could not explain this in his model and hence this became the only major drawback of his model.
