What type of intermolecular forces are present in He?

Helium (He) is a noble gas and it is monoatomic. The only type of intermolecular force that exists between Helium atoms is the London dispersion force, also known as Van der Waals forces. These are the weakest type of intermolecular forces and they arise from the momentary shifts in electron density in the Helium atoms. This causes a temporary dipole to form, which induces a dipole in a neighboring atom, leading to a weak, transient force of attraction.
