Limitations of Rutherford atom model.

Following are the limitations of Rutherford atom model

(i) According to electromagnetic theory a revolving electron should continuously emit energy and hence the radius of its path should go on decreasing and ultimately,it should fall into the nucleus. However, electrons revolve around the nucleus without falling in it. Hence, Rutherford atom model cannot explain the stability of atom.

(ii) Rutherford model cannot explain line spectra of atoms like hydrogen. Because if the Rutherford atom model is true, the electrons can revolve in orbits of all possible radii hence, it should emit continuous energy spectrum.
