He or he2

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. WebHelium (He) Electron Configuration and Orbital Diagram Helium is the 2nd element in the periodic table and its symbol is ‘He’. In this article, I have discussed in detail how to easily write the complete electron configuration of helium. I also discussed how to draw and write an orbital diagram of helium.
