WebRutherford designed an experiment for this. In this experiment, fast moving alpha (α)-particles were made to fall on a thin gold foil. He selected a gold foil because he wanted as thin a layer as possible. This gold foil was about 1000 atoms thick. α-particles are doubly-charged helium ions. WebAn experiment was carried out to direct alpha particles at a thin gold foil. The plum pudding model suggested that mass and charge were evenly spread throughout the atom.
