Rutherford’s model of an atom was able to explain a lot about the structure of atom. Although it has a few drawbacks as well. According to this model the atom would not be stable. This phenomenon can be explained as follows:

According to this model, the orbital revolution of the electron is not expected to be stable. Any particle which is in a circular orbit would undergo an acceleration. Charged particles would radiate energy during acceleration. Electrons are negatively charged. Thus, the revolving electron would lose energy. It will finally fall into the nucleus. If this was the situation, then the atom should be highly unstable. Hence, matter would not exist in the form that we know.
