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. WebRutherford’s Experiment By the early 1900s, scientists had determined the charge and mass of the negative subatomic particles—the electrons.

WebRutherford and Royds made a direct identification of the alpha particle in 1909. The apparatus they used is shown in Figure 1 Radon gas, an alpha-emitter, was enclosed in a glass tube A that had walls only 0.01 mm thick. The tube B was originally evacuated. After a week the mercury level in B was raised and a discharge struck, forming a spectrum.
