( ncert solution of atoms ) Rutherford’s nuclear model was a major step towards how we see the atom today. However, it could not explain why atoms emit light of only discrete wavelengths. How could an atom as simple as hydrogen, consisting of a single electron and a single proton, emit a complex spectrum of specific wavelengths? In the classical picture of an atom, the electron revolves around the nucleus much like the way a planet revolves around the sun. However, we shall see that there are some serious difficulties in accepting such a model.
