WebErnest Rutherford. Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, PRS, HonFRSE [4] (30 August 1871 – 19 October 1937) was a New Zealand physicist who came to be known as the father of nuclear physics. [5] … 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.

WebRutherford overturned Thomson’s model in 1911 with his famous gold-foil experiment, in which he demonstrated that the atom has a tiny, massive nucleus. Five years earlier Rutherford had noticed that alpha particles beamed through a hole onto a photographic plate would make a sharp-edged picture, while alpha particles beamed through a sheet of …

WebGamma rays Six years after the discovery of radioactivity (1896) by Henri Becquerel of France, the New Zealand-born British physicist Ernest Rutherford found that three different kinds of radiation are emitted in the decay of radioactive substances; these he called alpha, beta, and gamma rays in sequence of their ability to penetrate matter.
WebThe only explanation for this was that the entire positive charge in an atom, the charge that would repel an alpha particle, must be concentrated in a very small area. An area that he called the nucleus.
