Question

DRAWBACKS OF RUTHERFORD MODEL OF ATOM​

Answer 1

·Rutherford’s atomic model could not explain how the moving electrons could remain in its orbit.

·Any charged particle during acceleration would give out energy; and while revolving it would lose energy and eventually fall into the nucleus.

·This means that the atom would be highly unstable.

·But, matter is composed of stable atoms.

·Thus, the major drawback of Rutherford’s atomic model was that it could not explain the stability of atoms.

Answer 2

║⊕ANSWER⊕║

• Rutherford's model was unable to explain the stability of an atom.
• According to Rutherford's postulate, electrons revolve at a very high speed around a nucleus of an atom in a fixed orbit. However, Maxwell explained accelerated charged particles release electromagnetic radiations.
• As the electrons move in circular path, they should undergo acceleration and radiate energy. The radiation of energy would result in the electron losing energy and finally collide with the nucleus. This would mean that the atom would become highly unstable. Rutherford failed to explain this in his atomic model
