At Cambridge, Rutherford started to work with J. J. Thomson on the conductive effects of X-rays on gases, work which led to the discovery of the electron which Thomson presented to the world in 1897. Hearing of Becquerel's experience with uranium, Rutherford started to explore its radioactivity, discovering two types that differed from X-rays in their penetrating power. Continuing his research in … WebRutherford was also able to show that the number of swift atoms of oxygen produced by the alpha-particle collisions was about the same as the corresponding number of hydrogen …

WebApr 8, 2024 · In 1909, Rutherford discovered protons in his famous gold foil experiment. He bombarded alpha particles on an ultrathin gold foil. Rutherford thought that a hydrogen nucleus must be the fundamental building block of all nuclei, and also possibly a new fundamental particle as well since nothing was known from the nucleus that was lighter.

As early as 1815, William Prout proposed that all atoms are composed of hydrogen atoms (which he called "protyles"), based on a simplistic interpretation of early values of atomic weights (see Prout's hypothesis), which was disproved when more accurate values were measured.

WebThe proton was first postulated by Rutherford in his gold foil experiment in which he found that the vast majority of alpha particles passed straight through a sheet of gold foil, but occasionally one would bounce back. He reasoned that this could only be due to a very small, dense and positively charged particle inside the atom.
