According to Thomson’s atomic model electrons were embedded in a sphere of positive charge. This implies that according to Rutherford’s gold foil experiment in which the alpha particles which are positively charged must be reflected or deflected in large numbers but after performing the experiment it was being found out that most of the alpha particles pass straight through. This observation clearly meant that most of the space inside an atom is empty which was contrary to that predicted in Thompson’s model. Hence, Ernest Rutherford got unexpected results from his experiment.
