Rutherford model - Wikipedia

The Rutherford model was devised by the New Zealand-born physicist Ernest Rutherford to describe an atom.Rutherford directed the 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 new features of a relatively ...
