Noble gas elements form compounds only with fluorine and oxygen. Explain.

Text Solution

Verified by Experts

Noble gas elements have highly symmetrical electronic configuration and therefore, high ionisation enthalpies. Since all their occupied orbitals are filled, they normally cannot form any compounds. However, the elements fluorine and `d-`orbitals. This, too, is possible mainly in case of xenon in which the ionisation enthalpy is the minimum and the promotion of electrons is rather easy. No other elements are in a position to form compounds with noble gas elements.
