Molecular orbital diagram for he2 2. Molecular orbital diagram for carbon dimer c2. This mix to form a sigma orbital from h1sli2s a sigma orbital and h1s li2s and a non bonding orbital from li1s lower in energy than the sigma. Please note the diagram is for he2 but the he h is very similar.

Chemical bonding chemical bonding molecular orbitals of h2 and he2. Its molecular orbitals are constructed from the valence shell orbitals of each hydrogen atom which are the 1s orbitals of the atoms. Two superpositions of these two orbitals can be formed one by summing the orbitals and the other by taking their difference.
