Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.
Hydrogen has three isotopes
hydrogen
Hydrogen is not radioactive; its two most common isotopes are stable.
It really isn't elements that are stable or unstable, but isotopes. Carbon has both stable and unstable isotopes.
Xenon has eight stable naturally occuring isotopes. Besides these stable forms, there are over 40 unstable isotopes that have been studied.
Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.
Hydrogen has three isotopes
hydrogen

Hydrogen is not radioactive; its two most common isotopes are stable.
The isotopes protium (H-1) and deuterium (H-2) are stable; tritium (H-3) and artificial isotopes are unstable.
Radioactive isotopes are not stable.
Stable isotopes are used as tracers.
copper has 2 stable isotopes
Isotopes of hydrogen are Hydrogen-1 (protium), ‎Hydrogen-2 (deuterium), ‎and Hydrogen-3 (tritium).
