This indicates that there is no … WebTwo electrons total, both occupy the sigma orbital, two more electrons in bonding than antibonding orbitals, the compound is stable. Eg: He + He; same mixing as above. Four electrons, two in the sigma, two in the sigma*. Since there are as many bonding electrons as as antibonding, there is no net bond. He2 is not possible. The helium dimer is a van der Waals molecule with formula He2 consisting of two helium atoms. This chemical is the largest diatomic molecule—a molecule consisting of two atoms bonded together. The bond that holds this dimer together is so weak that it will break if the molecule rotates, or vibrates too much. It can only exist at very low cryogenic temperatures. fixing megaforce
