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 has 1 as its atomic number. That's because it has one proton in its nucleus. Hydrogen has three isotopes. Each isotope has one proton in its nucleus (naturally, â¦ because that's what makes it hydrogen). Atomic mass is the number of protons plus the number of neutrons in an atom's nucleus.Let's look at each isotope of hydrogen.  Simple hydrogen has only the 1 proton in its nucleus.ydrogen has three isotopes. Each isotope has one proton in its nucleus (naturally, â¦ because that's what makes it hydrogen).
