Van der Waals forces are an intermolecular force of attraction between atoms or molecules.
They are significant when there are no other intermolecular forces present [1].
They are formed from the movement of electrons within the atom or molecule creating a temporary dipole-dipole (even if the atom/molecule does not have a net charge). An electrostatic attraction forms between the temporarily positive area of one molecule and temporarily negative area of another [2].
