Webproof that the α particle after loosing its charge is an atom of helium (Rutherford and Royds 1909, p. 166). While primarily investigating radioactivity from an experimental perspective, Rutherford was also keenly interested in explaining the phenomenon in causal terms. The origin of radioactivity was at the time a complete mystery, but 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.
