Q. 3. What are the limitations of Rutherford's model of the atom ? Ans. It was pointed by Neils Bohr that Rutherford's atom should be highly unstable. He argued that if an electron (charged particle) moves around the nucleus in an orbit, it should be subjected to acceleration due to continuous change in its direction of motion. Therefore, the electrons should continuously emit radiations and lose energy. Consequently, the orbit should become smaller and smaller and ultimately the electron should fall into the nucleus. In other words, the atom should collapse. Since the atoms do not collapse, therefore, there must be something wrong with the Rutherford's model of atom. Another serious drawback of the Rutherford's model of an atom is that it says nothing about the electronic structure of atom, i.e., how electrons are distributed Fig. : Limitation of Rutherford's model around the nucleus and what are the energies of these electrons. of the atom
