What is the primary difference between intermolecular and interatomic forces?

Intermolecular forces act between atoms, while interatomic forces act between molecules.

Intermolecular forces act between molecules or between molecules and ions, while interatomic forces hold atoms together within a molecule. (correct)

Intermolecular forces are generally stronger than interatomic forces.

Intermolecular forces include ionic, covalent, and metallic bonds, while interatomic forces include dipole-dipole and London dispersion forces.

How does molecular size affect the strength of London dispersion forces?

Larger molecules have weaker London dispersion forces.

Molecular size has no effect on the strength of London dispersion forces.

Larger molecules have stronger London dispersion forces, but only if they are non-polar.

Larger molecules have stronger London dispersion forces due to greater fluctuations in electron distribution. (correct)
