2. It could not explain large angle scattering of α – particles. Rutherford’s Atomic Model On the basis of this experiment, Rutherford made following observations (i) The entire positive charge and almost entire mass of the atom is concentrated at its centre in a very tiny region of the order of 10-15 m, called nucleus.
