WebJan 18, 2024 · Rutherford's atomic model became known as the nuclear model. Most of the α -particles were not scattered; they passed unchanged through the thin metal foil. Some of the few that were scattered were scattered in the backward direction; i.e. they recoiled. This backward scattering requires that the foil contain heavy particles.
