What elements isotopes are protium, deuterium, and tritium?

Protium, deuterium, and tritium are all isotopes of hydrogen, which means they are different forms of the same element that have the same number of protons but different numbers of neutrons. Protium is the most common isotope and has no neutrons, deuterium has one neutron, and tritium has two neutrons. This distinction in neutron count leads to variations in their atomic mass, but all three isotopes retain the chemical properties associated with hydrogen, such as forming bonds in similar ways. Recognizing the specific isotopes connected to hydrogen is crucial in understanding topics such as nuclear chemistry and the behavior of these isotopes in various chemical reactions.
