WebFeb 12, 2024 · Rutherford's Nobel-winning discovery of α particles formed the basis of the gold foil experiment, which cast doubt on the plum pudding model. WebApr 27, 2014 · Rutherford proposed that the atom is mostly empty space. The electrons revolve in circular orbits about a massive positive charge at the centre. His model explained why most of the α particles passed straight through the foil. The small positive nucleus would deflect the few particles that came close.
