Why do all/most atoms have London dispersion forces?

All atoms have the potential to form temporary dipoles, due to electrons randomly moving into favorable positions. These temporary dipoles are London Forces.

All atoms have London dispersion forces because all atoms have electrons that are constantly moving around the atom and can temporarily congregate to one side. The more electrons present and the larger an atom is, the stronger these forces will be.

Since electron's are constantly moving, there is potential for a temporary dipole to be present (the electrons would happen to be more towards one side).

Due to electrons always moving around and never staying in one set place, they sometimes create temporary dipole moments, which is why there are london forces in every bond.
