A Noble Gas Surprise: Helium Can Form Weird Compounds

WebThe helium dimer is a van der Waals molecule with formula He 2 consisting of two helium atoms. This chemical is the largest diatomic molecule—a molecule consisting of two atoms bonded together. The bond that holds this dimer together is so weak that it will break if the molecule rotates, or vibrates too much. It can only exist at very low cryogenic temperatures. WebElements that form ions do so because their natural electron configuration isn’t stable. By gaining or losing electrons they can attain a full valence shell, i.e. that of a noble gas, which is stable. Elements that already have full shells, and smaller atoms that have half-filled shells, such as carbon and silicon, typically don’t form ions ...
