The proton was discovered in 1918 by Ernest Rutherford. He noticed that when alpha particles were shot into nitrogen gas, his scintillation detectors showed the signatures of hydrogen nuclei. Rutherford determined that the only place this hydrogen could have come from was the nitrogen, and therefore nitrogen must contain hydrogen nuclei. He thus suggested that the hydrogen nucleus, which was known to have an atomic number of 1, was an elementary particle. This he named proton, from protos, the Greek for "first".

Discovery of the ProtonIn the early 1920's after the discovery of the electron, Rutherford and other physicists made a number experiments, transmuting one atom into another. In every case, hydrogen nuclei were emitted in the process. It was apparent that the hydrogen nucleus played a fundamental role in atomic structure, and by the late 1920's physicists were regularly referring to hydrogen nuclei as 'protons'. The term proton itself seems to have been coined by Rutherford, and first appears in print in 1920.

Proton was discovered by E. Rutherford in 1917. Electron was discovered by J. J. Thompson in 1897. Neutron was discovered by J. Chadwick in 1932. All were of English origin.

The scientist that discovered protons is not certain, but Ernest Rutherford discovered the nucleus of an atom in 1911 after J.J. Thompson discovered the electron in 1897. Rutherford is generally given the credit for discovering the proton.

Answered by Bushra wali.The particles of the atom that is ;Electron,Proton,neutron are not discovered by the same person but they are discovered by different person. Discoverer of Electron.The electron which carry a negative charge is discovered by Joseph Jhon Thomson.Discoverer of Proton and Neutron'The proton is discovered by Rutherford where as neutron is discover by chadwick.

Neither of them. No one invented the proton. It was always there, someone just discovered it.

actually anode rays are discovered by gold steen,and rutherford gave the name proton for that.so we say those two answers.
