WebStable isotopes built from helium nuclei (alpha particles) * The most abundant form of solar argon 36 18 Ar is primordial — forged in the cores of the long dead ancestors of the Sun. The most abundant isotope of atmospheric argon 40 18 Ar is radiogenic — the decay product of radioactive potassium that escaped the Earth's crust.; alpha The shortest-lived isotope is helium-10 with a half-life of 260(40) yoctoseconds. Helium-6 decays by emitting a beta particle and has a half-life of 806.92(24) milliseconds. The most widely studied heavy helium isotope is helium-8. This isotope, as well as helium-6, is thought to consist of a normal … See more 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.

"In the perspective of quantum mechanics, helium is the second simplest atom to model, following the hydrogen atom. Helium is composed of two electrons in atomic orbitals surrounding a nucleus containing two protons and (usually) two neutrons. As in Newtonian mechanics, no system that consists of more than two particles can be solved with an exact analytical mathematical approach (see 3-body problem) and helium is no exception. Thus, numerical mathematical methods are re… " - Most abundant isotope of helium
