WebApr 1, 2024 · Each hydrogen atom contributes one 1s atomic orbital, and thus, the orbitals overlap according to MO theory to form one σ1s and one σ* 1s MO by conservation of orbitals. If you calculate their bond order, you get: BOH+ 2 = 1 2(Bonding − Antibonding) = 1 2 (1 − 0) = 1 2 BOH− 2 = 1 2(Bonding − Antibonding) = 1 2 (2 − 1) = 1 2 Based on molecular orbital theory, He2 should not exist, and a chemical bond cannot form between the atoms. However, the van der Waals force exists between helium atoms as shown by the existence of liquid helium, and at a certain range of distances between atoms the attraction exceeds the repulsion. So a molecule composed of two helium atoms bound by the van der Waals force can exist. The existence of this molecule was proposed as early as 1930.
