Radioisotope helium
Helium-2 or He is an extremely unstable isotope of helium. Its nucleus, a diproton, consists of two protons with no neutrons. According to theoretical calculations, it would have been much more stable (although still undergoing β decay to deuterium) if the strong interaction had been 2% greater. Its instability is due to … Ver más Although there are nine known isotopes of helium (2He) (standard atomic weight: 4.002602(2)), only helium-3 ( He ) and helium-4 ( He ) are stable. All radioisotopes are short-lived, the longest-lived being He with a Ver más The most common isotope, He , is produced on Earth by alpha decay of heavier radioactive elements; the alpha particles that … Ver más • General Tables — abstracts for helium and other exotic light nuclei Ver más He is stable and is the only stable isotope other than H with more protons than neutrons.
