Can helium become a solid
WebOct 14, 2024 · The first sentence should read, "Yes, gases can diffuse into and through metal, some problematically so." I don't know of any evidence that there's a subset of gases that don't diffuse through metal. Not really, but sort of. Helium atoms do not form molecules, and the atoms are small. 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…

Trying to create a solid from pure Helium is basically the same as arranging all Helium atoms in a crystal lattice and telling them to stay put. This is equivalent to putting each in a little "box", bounded by the neighboring atoms.
