At a given temperature and pressure, the density of a gas is proportional to its molecular weight. In theory, the next lightest gas after helium would be borane, BHâ (13.8 amu) but it exists as a minor component in equilibrium with its dimer, BâHâ (27.6 amu) and canât be obtained as a pure gas. The true next lightest gases would be methane, CHâ (16 amu), ammonia, NHâ (17 amu), hydrogen fluoride, HF (20 amu), and neon (20.2 amu). Because nitrogen, oxygen, and fluorine are all diatomic, their molecular weights are 28, 32, and 38 atomic mass units, respectively, and they are therefore denser than neon.
