He2 stable or unstable

Why helium exist as he Whereas hydrogen exists as H2?

WebAnswer (1 of 11): According to molecular orbital theory, H2+ has an unpaired electron in the bonding orbital. This is a higher energy state than H2, which has a pair of electrons in the bonding orbital. The lone electron in H2+ is known as a free radical. Free radicals attack … 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 spin–spin interactions in the nuclear force, and the Pauli exclusion principle, which forces the two protons to have anti-aligned spins and gives the diproton a negative bindin…
