Hydrogen has 1 unstable isotope, and 2 stable isotopes.
Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.
Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.
Hydrogen has three stable isotopes: protium (1H), deuterium (2H), and tritium (3H). Among these, protium is the most abundant, making up over 99.98% of naturally occurring hydrogen.
hydrogen
The lightest element on the periodic table with no stable isotopes is hydrogen. It only has one proton in its nucleus and no stable isotopes.
Technetium (Tc) is the element that has no stable isotopes. All of its isotopes are radioactive with half-lives ranging from minutes to millions of years.
The isotopes protium (H-1) and deuterium (H-2) are stable; tritium (H-3) and artificial isotopes are unstable.
