Answer   Hydrogen is composed of one proton and one electron.   Some isotopes of hydrogen are slightly different. Deuterium contains one proton, one neutron, an â¦ d one electron. Tritium contains one proton, two neutrons, and one electron.
Protons have a positive charge and a mass 1,836 times that of the electron, at 6973167260000000000â 1.6726Ã10â27 kg. The number of protons in an atom is called its atomic number. Ernest Rutherford (1919) observed that nitrogen under alpha-particle bombardment ejects what appeared to be hydrogen nuclei.
