(B) According to the plum pudding model (top), all of the alpha … WebThis led Rutherford to propose the nuclear model, in which an atom consists of a very small, positively charged nucleus surrounded by the negatively charged electrons. Based on the number of \alpha α particles deflected in his experiment, Rutherford calculated that the nucleus took up a tiny fraction of the volume of the atom.
