WEBHelium dimer. The helium dimer is a van der Waals molecule with formula He 2 consisting of two helium atoms. [2] . 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.

When we bring the 2 atoms next to each other, we can make 2 MOs out of the 2 1s AOs. As always, we will do a + combination and a — combination. These combinations are illustrated in the figure below.

WEBSep 12, 2022 · A dihydrogen molecule (H 2) forms from two hydrogen atoms. When the atomic orbitals of the two atoms combine, the electrons occupy the molecular orbital of lowest energy, the σ 1s bonding orbital. A dihydrogen molecule, H 2, readily forms because the energy of a H 2 molecule is lower than that of two H atoms.
