Exciting history is connected with the discoveries of noble-gases and their chemical compounds [1][2]. In this talk some milestones of noble gas chemistry are highlighted. The main focus is in noble-gas hydrides of structure HXY, where Y is Ar, Kr or Xe and Y an electronegative atom or fragment. Examples of various experimentally and computationally characterized compounds are given. Interactions of these molecules with other substances are of interest for learning their reactivity and possible external stabilization effects [3][4]. HXeBr in solid CO2 is the first example of a noble-gas hydride in a molecular solid  [5], and in this medium strong blue shift of the H-Xe stretching is observed, indicating strong stabilization of the H-Xe bond.
