Dispersion forces are attractions that occur due to the random electronic motion within all substances, those that are nonpolar. when the electrons within a molecule or atom are distributed asymmetrically about the nucleus, that molecule or atom will adopt a dipole. the presence of this dipole can then distort the electrons of a neighboring atom or molecule, producing an dipole. these two rapidly fluctuating dipoles thus result in a brief electrostatic between the two species. these forces are stronger in atoms and molecules. for example, dispersion forces between iodine molecules will be stronger than dispersion forces between fluorine molecules.

Explanation:

Dispersion forces are weakelectrostatic attractions that occur due to the random electronic motion within all substances, such as those that are nonpolar. When the electrons within a molecule or atom are distributed asymmetrically about the nucleus, that molecule or atom will adopt a shortlived, instantaneous _ dipole. The presence of this dipole can then distort the electrons of a neighboring atom or molecule, producing an _induced__ dipole. These two rapidly fluctuating dipoles thus result in a brief electrostatic _attraction_ between the two species. These forces are stronger in larger and weighty_ atoms and molecules. For example, dispersion forces between iodine molecules will be stronger than dispersion forces between fluorine molecules.
