Drawbacks of Rutherford’s Model of an Atom

·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.
