Splet27. jan. 2024 · Helium has the lowest melting point and boiling point of the elements, so it only exists as a gas, except under extreme conditions. At normal pressure, helium is a liquid at absolute zero. It must be pressurized to become solid. Helium is the second-lightest element. The lightest element or one with the lowest density is hydrogen.

SpletSpherically shaped molecules generally have relatively high melting points, which in some cases approach the boiling point. This reflects the fact that spheres can pack together more closely than other shapes. This structure or shape sensitivity is one of the reasons that melting points are widely used to identify specific compounds.
