How did rutherford discover protons

WebBetween 1908 and 1913, Rutherford, Geiger, and Marsden ran a series of experiments where they pointed a beam of alpha particles at a thin foil of metal and, [7] using the scintillation method devised by Crookes, Elster, and Geitel, [8] [9] studied the scattering pattern of the alpha particles with the aid of a fluorescent screen. WebDiscovery of the Neutron. It is remarkable that the neutron was not discovered until 1932 when James Chadwick used scattering data to calculate the mass of this neutral particle. Since the time of Rutherford it had been known that the atomic mass number A of nuclei is a bit more than twice the atomic number Z for most atoms and that essentially all the …
