I have a confusion with this answer...is it Ernest Rutherford or E Goldstein? It was Ernest Rutherford who discovered proton in the year 1917. who discovered protons, neutrons and electrons? It is not always clear who discovered the proton because the process of the discovery was slow and gradual, and many scientists contributed. Based on the conclusions drawn from the gold-foil experiment, Rutherford is also credited with the discovery of the atomic nucleus. All of Rutherford’s experiments involved atom transmuting and the end result was always hydrogen nuclei emission, and the fact that hydrogen has an atomic number of 1 further strengthened the point that the hydrogen nucleus played a major role and was a fundamental particle of the atom. Then in 1919 Rutherford further discovered that striking an element with energetic alpha particles would change it and the discovery of the proton was underway. In 1899, Rutherford discovered alpha and beta ‘rays’ from uranium. Who discovered protons? Next Rutherford started shooting alpha particles towards neon particles and concluded during these experiments that the hydrogen element had to be the building blocks of atoms; these experiments showed physicists that the hydrogen nucleus was a fundamental element in the atomic structure and by comparing nuclear masses to their charges it was discovered that a nucleus’s positive charges were related to an integer number of hydrogen nuclei. John Dalton (late 1700s) was the first to perform experiments that determined atomic weight. The discovery of protons can be attributed to Rutherford. Answer Save.
