WebCathode Ray Experiment. J. J. Thomson discovered the existence of electrons. ... Rutherford’s Model of an Atom. Rutherford concluded the model of the atom from the α-particle scattering experiment as follows: (i) There is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus. WebIn 1909 Rutherford carried out the gold foil experiment in which he discovered the nuclear nature of atoms by deflecting alpha particles through a thin gold foil. Rutherford's idea was to look for alpha particles with very high deflection angles, angles that were not expected from any theory of matter at the time.
