Key Concepts

Mass Ratio

The mass ratio refers to the relative atomic masses of the isotopes. For hydrogen, assuming each nucleon contributes roughly the same amount to the total mass, the ratios for protium, deuterium, and tritium are approximately 1:2:3, reflecting their respective numbers of nucleons.

Hydrogen Isotopes

Hydrogen has three natural isotopes: protium, deuterium, and tritium. Protium has no neutrons, deuterium has one neutron, and tritium has two neutrons. These differences in neutron count lead to variations in mass while maintaining the same chemical behavior characteristic of hydrogen.

Isotopes

Isotopes are variants of a chemical element that have the same number of protons but differ in the number of neutrons. This difference results in distinct atomic masses while the isotopes generally share the same chemical properties.
