The atomic nucleus was discovered by Ernest Rutherford in 1911. In 1913, it was proven that the charge of the nucleus was equal to its atomic number. In 1919, Rutherford proved that the nuclei of all atoms contained particles described as hydrogen nuclei, and this is considered the discovery of the proton.

Binomial particles like protons, neutrons, and electrons were discovered by multiple scientists. The electron was discovered by J.J. Thomson in 1897, the proton was discovered by Ernest Rutherford in 1919, and the neutron was discovered by James Chadwick in 1932.

Scientists who discovered protons?

Protons were discovered when the nucleus of atoms were discovered. Electrons were already known about, so when the nucleus was discovered, it was known that it had to contain positively charged particles: protons. The nucleus was discovered by Ernest Rutherford by shooting alpha particles (helium nuclei, basically helium without the electrons) at a thin sheet of gold. Most of the alpha particles went straight through, but some if them were scattered. Rutherford deduced that these particles had hit something in the foil that didn't take up a large percentage of space: the nuclei of the gold atoms.
