Question
State the limitation of alpha scattering experiment.
Solution
Limitation of Rutherford's alpha-particle scattering experiment:
In the model, it was proposed that the electron is revolving aroung the nucleus and is continuously experiencing a centripetal force. Thus, the electron has an accelerated motion. And, as per classical theory, the electron must radiate energy in the form of electromagnetic waves. So, the revolving electron is constantly losing energy and, it must spiral inwards eventually, falling into the nucleus.
But, since the matter is stable, the atom is not expected to collapse. This was a major drawback of rutherford's model.
