WebErnest Rutherford bombarded nitrogen atoms with helium nuclei (alpha particles), and hydrogen atoms (protons) were formed as a result. From this, he concluded that … WebThe next step in the journey—the discovery of atomic nuclei consisting of protons and neutrons—was made by the New Zealand-born British scientist Ernest Rutherford, and his students. Rutherford’s experimental work was designed to identify the nature of radioactivity, which Marie Curie had discovered in 1897.
WebRutherford had discovered the atomic nucleus in 1911, and had observed the proton in 1919. However, it seemed there must be something in the nucleus in addition to protons. For instance, helium was known to have … WebA third type of radiation, γ rays, was discovered somewhat later and found to be similar to the lower-energy form of radiation called x-rays, now used to produce images of bones and teeth.

WebTwelve years earlier, Lord Ernest Rutherford, a pioneer in atomic structure, had postulated the existence of a neutral particle, with the approximate mass of a proton, that could result from the capture of an electron by a proton. This postulation stimulated a … WebBetween 1908 and 1913, Rutherford, Geiger, and Marsden ran a series of experiments where they pointed a beam of alpha particles at a thin foil of metal and, [7] using the scintillation method devised by Crookes, Elster, and Geitel, [8] [9] studied the scattering pattern of the alpha particles with the aid of a fluorescent screen.
