Which is the weakest intermolecular force, considered as the Van der Waals force, often found in halogens, noble gases and other non-polar molecules?

Explanation

First explained mathematically by Fritz London in 1930, London dispersion forces are definitively the weakest type of intermolecular attraction. They arise from temporary, rapidly fluctuating dipole moments in electron clouds and are the only attractive forces present between non-polar molecules and noble gases.
