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 meth… tartan sherpa lambswool blanketWebNov 14, 2024 · A monoatomic ideal gas has mean energy 3 2 k T per particle, or a molar heat capacity of 3 2 R, where R is the ideal gas constant.
