The noble gases have a particularly stable electronic configuration, comprising fully filled s and p valence orbitals. This makes these elements relatively non-reactive, and they exist at room temperature as monatomic gases. Pauling predicted in 1933 that the heavier noble gases, whose valence electrons are screened by core electrons and thus less strongly bound, could form stable molecules. This prediction was verified in 1962 by the preparation of xenon hexafluoroplatinate, XePtF6, the first… 
Lifetime of a Chemically Bound Helium Compound
The rare-gas atoms are chemically inert, to an extent unique among all elements. This is due to the stable electronic structure of the atoms. Stable molecules with chemically bound rare-gas atoms
Silicon compounds of neon and argon.
The use of the SiF3 2+ dication as a superelectrophilic reagent with particularly favorable properties for the generation of noble gas compounds is addressed, which is a promising candidate for the formation of new noble gas heteroatom bonds.
Formation of Potential Interstellar Noble Gas Molecules in Gas and Adsorbed Phases
This work shows that the noble gas molecules ArCCH+, ArOH+, ArNH+, and NeCCH+ are not only stable minima on their respective potential energy surfaces but also can be formed in either the gas phase or through PAH adsorption with known or hypothesized interstellar molecules.
Noble Gas-Actinide Compounds: Complexation of the CUO Molecule by Ar, Kr, and Xe Atoms in Noble Gas Matrices
The experimental and theoretical results suggest that multiple argon atoms can bind to a single CUO molecule, as well as predicting that CUO can bind directly to one argon atom.

Geometric as well as energetic considerations along with AIM results suggest a partial covalent nature of Au-Ng bonds in these systems, which might have important implications in the preparation of a new class of insertion compounds of noble-gas atoms containing noble- gas-noble-metal bond.
Noble Gases: Inorganic Chemistry
The noble gas (Ng) elements have a rich reaction chemistry despite having a filled valence shell that would indicate otherwise. Halide compounds, usually with fluorine, and various oxides are common.
Reactivity of He with ionic compounds under high pressure
The authors demonstrate the driving force for helium reactivity, showing that it can form new compounds under pressure without forming any local chemical bonds.
Noble gas hydrides in the triplet state: HNgCCO+ (Ng = He, Ne, Ar, Kr, and Xe).
A new series of noble gas hydrides in the triplet state is explored and results ultimately indicate that these predicted species may be prepared and characterized by suitable experimental technique(s) under a cryogenic environment.
Noble‐Noble Strong Union: Gold at Its Best to Make a Bond with a Noble Gas Atom
Noble metals, particularly gold, provide the opportunity for experimental chemists to obtain sufficiently stable complexes with Ng at room temperature in order to characterize them by using experimental techniques and, with the intriguing bonding situation, to explore them with various computational tools from a theoretical perspective.
Stable Lithium Argon compounds under high pressure
A detailed analysis of the electronic structure of LiAr and Li3Ar shows that Ar in these compounds attracts electrons and thus behaves as an oxidizing agent, markedly different from the hitherto established chemical reactivity of Ar.
