Quizplus · Accepted Answer

All isotopes of hydrogen have the same atomic number, which is 1. This means they all have one proton in their nucleus, which is the defining characteristic of hydrogen. The differences among isotopes of hydrogen (such as protium, deuterium, and tritium) lie in the number of neutrons in the nucleus, not the number of protons.
