Answer
Noble gases have their outermost or valence shell complete i.e., they have 2 electrons in outermost shell e.g., helium [electronic configuration 2] or they have 8 electrons in outermost shell e.g., neon [electronic configuration 2,8] or argon [electronic configuration 2,8,8 ]. So, they have stable electronic configuration. They do not gain, lose or share electrons and are unreactive or inert. Hence, they do not form compounds readily.
