Dispersion forces, also known as London dispersion forces, are the most basic type of intermolecular force. Despite being the weakest kind, they are present in all molecules. These forces arise because electrons within an atom's electron cloud are constantly in motion, causing temporary unevenness in charge distribution. This temporary change generates a temporary dipole that can induce further temporary dipoles in nearby molecules or atoms.

In particular, dispersion forces are significant between nonpolar molecules and noble gases like neon, where other types of intermolecular forces are absent. While they are momentary, these forces can sum up to appreciable strengths, especially in larger and more massive atoms or molecules because they have larger, more easily polarizable electron clouds. Nevertheless, for smaller atoms like neon, dispersion forces remain quite weak. It's important to remember that without dispersion forces, even noble gases wouldn't condense into liquids at low temperatures.

Dipole-induced dipole forces are intriguing because they involve both polar and nonpolar molecules in bringing about intermolecular attraction. When a polar molecule, which has a permanent dipole, approaches a nonpolar molecule, its electric field can shift the electrons within the nonpolar molecule. This shift induces a temporary dipole in the otherwise nonpolar molecule.

However, in the case of interactions between two neon atoms, dipole-induced dipole forces do not come into play. Neon is a noble gas that is nonpolar, meaning it does not have the necessary permanent dipole needed to induce a dipole in another atom. For dipole-induced dipole interactions to occur, there must be at least one polar molecule involved, which is absent in neon-neon interactions.

Noble gases, such as neon, make up a unique group of elements located in Group 18 of the periodic table. Known for their inertness, these gases have full electron shells, which gives them great stability and low reactivity. Because they don't easily form bonds with other atoms, most intermolecular attractions in noble gases are limited to weak dispersion forces.

This is the reason why noble gases can exist as monatomic gases under standard conditions. Even though dispersion forces exist between noble gas atoms, like in neon, these forces are remarkably weak due to the small size and low polarizability of the gas atoms. Full electron shells mean there is little opportunity for interactions with other gas atoms, explaining why noble gases like neon remain gases at room temperatures and require extremely low temperatures to condense into liquids.
