Atomic Numbers Vs. Melting Points Sciencing

WebThe melting and boiling points of pure substances reflect these intermolecular forces, and are commonly used for identification. Of these two, the boiling point is considered the most representative measure of general intermolecular attractions. ... Neon is heavier than methane, but it boils 84º lower. WebThe melting and boiling points of noble gases are very low in comparison to those of other substances of comparable atomic and molecular masses. This indicates that only weak van der Waals forces or weak London … WebA methane molecule is larger than a neon atom. Because the electrons in methane molecules are dispersed over a larger area and their distribution (in space) ... Remember that intermolecular forces determine physical properties such as boiling point and melting point while intramolecular forces are between molecules (ionic, covalent ... marley from home alone
