The discovery of protons can be attributed to Rutherford.
In 1886 Goldstein discovered the existence of positively charged rays in the discharge tube by using a perforated cathode. These rays were named anode rays or canal rays.
In 1899, Rutherford discovered alpha and beta ‘rays’ from uranium. He later demonstrated that alpha rays are the nuclei of helium atoms. He discovered in 1914 that the nucleus of an atom constituted an extremely dense but small fraction of the volume of an atom and that this nucleus was positive in charge.
Given the discoveries of electrons in 1897 by Thomson, Rutherford and other scientists decided that a positively charged particle must exist to center the electron to create equally neutral atoms.
Thompson proposed the name ‘positive rays’. Rutherford, in 1914, suggested that this something that was positively charged or the sportive ray of Thompson was a particle.
He gave the name ‘positive electron’ to it. The word ‘proton’ was assigned to this particle by 1920.
Rutherford continued to do research until his death, but the proton was his last big discovery.
