Density helium gas

In the perspective of quantum mechanics, helium is the second simplest atom to model, following the hydrogen atom. Helium is composed of two electrons in atomic orbitals surrounding a nucleus containing two protons and (usually) two neutrons. As in Newtonian mechanics, no system that consists of more than two particles can be solved with an exact analytical mathematical approach (see 3-body problem) and helium is no exception. Thus, numerical mathematical methods are re… WebThe density of helium (molecular weight 4) is one-seventh that of nitrogen (molecular weight 28). Replacing 70% nitrogen with 70% helium in a mixture with 30% oxygen would have the effect of decreasing the molecular weight (and therefore density) of the gas mixture from 29.2 to 12.4.
