Rutherford alpha ray
WebIn 1911 Rutherford made his greatest contribution to science with his nuclear theory of the atom. He had observed in Montreal that fast-moving alpha particles on passing through thin plates of mica produced diffuse images on photographic plates, whereas a sharp image was produced when there was no obstruction to the passage of the rays. WebDec 20, 2024 · Alpha rays are actually a stream of alpha particles traveling at very high rates of speed. Rutherford showed that an alpha particle is identical to a helium atom without its electrons, that is, a helium nucleus. Starting in 1909 Rutherford started experimenting with a gold foil that was bombarded wit beam of alpha particles.
