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.
Hydrogen always has one proton and one neutron. Isotopes of hydrogen from most to least common have zero, one, or two neutrons. Protium, with no neutrons and deuterium, with one neutron, are stable isotopes while tritium, with two neutrons, is radioactive and undergoes decay by beta particle emission.
