CERONI-GALLOSO, Mario  e  DURAND, Korali. Compounds of helium, neón and argón. Rev. Soc. Quím. Perú [online]. 2006, vol.72, n.4, pp.205-225. ISSN 1810-634X.

In this revision it is given to know the last investigations of the chemistry of the slightest GN: He, Ne and Ar. Because of the advances in research in this field, today it is essential to know deeply the chemistry of this group. It is mention the Pauling prediction (1933) that these elements can they form stable molecules, as He₂⁺ and  He ²⁺. The contribution of Neil Bartlett is pointed out when he obtained in 1962 the first 2 compound that contains an atom of GN, the xenon hexafluoroplatinato (XePtF₆), and 6 also the series of investigations that gave place to the obtaining of a series of made up with xenon and kripton. In the year 2000 the first stable compound of argon, HArF, was obtained and during the following years it has been to synthesize a similar of the helium. At the present time, many compound diatomics and poliatómics, but metaestables are known of helium and argon, low observables certain conditions in phase gas or to very low temperatures and other compounds that are investigated theoretically.
