8 ene 1909 año - Discovery of the Proton

Descripción:

Ernest Rutherford discovered the Proton in the year 1917.
Ernest Rutherford observed that his scintillation detectors detected hydrogen nuclei when a beam of alpha particles was shot into the air.
After investigating further, Rutherford found that these hydrogen nuclei were produced from the nitrogen atoms present in the atmosphere.
He then proceeded to fire beams of alpha particles into pure nitrogen gas and observed that a greater number of hydrogen nuclei were produced.
He concluded that the hydrogen nuclei originated from the nitrogen atom, proving that the hydrogen nucleus was a part of all other atoms.
The hydrogen nucleus was later named ‘proton’ and recognized as one of the building blocks of the atomic nucleus
