<P> The Rutherford model is a model of the atom devised by Ernest Rutherford . Rutherford directed the famous Geiger -- Marsden experiment in 1909 which suggested , upon Rutherford 's 1911 analysis , that J.J. Thomson 's plum pudding model of the atom was incorrect . Rutherford 's new model for the atom , based on the experimental results , contained the new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the atomic mass of the atom . This region would be known as the `` nucleus '' of the atom . </P>
