The noble gases have weak interatomic force, and consequently have very low melting and boiling points. They are all monatomic gases under standard conditions, including the elements with larger atomic masses than many normally solid elements.
INTERMOLECULAR FORCES. Intermolecular forces are noncovalent forces between molecules. There are a variety of these forces but the most common are: dipole-dipole interactions, hydrogen bonding and van der Waals (or London) forces. Of these, hydrogen bonds are the strongest followed by dipole-dipole interactions and finally, van der Waals forces.
