WebBased 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. The nuclear model explained Rutherford's experimental results, but it also raised further questions. For example, what were the electrons doing in the atom? Web23 de set. de 2024 · Rutherford's atomic model became known as the nuclear model. In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom. The electrons are distributed around the nucleus and occupy most of the volume of the atom.
