Inert gases are elements occupying a special place on the periodic table and referred to as noble gases. While the noble gases are most commonly found as monatomic elements, they can form compounds with other elements. Noble gases also form non-coalenvt compounds, for example clathrates that consist of an atom trapped within cavities of crystal lattices of organic and inorganic compounds. Noble gases can …

In addition to the compounds where a noble gas atom is involved in a covalent bond, noble gases also form non-covalent compounds.

    The process of formation of compound clathrate hydrate is likely to preferentially sequester some materials such as ethane and the noble gases (if any of the noble gases were initially present) in the cages. Ethane, which is constantly being produced in the upper atmosphere, may out‐compete methane for cages within the hydrate, providing a small source of methane to the atmosphere. Compound clathrate hydrates are nonstoichiometric crystal of guest molecules trapped inside cages of varying sizes formed by latticeworks of water molecules. They have shorter induction periods and faster reaction rates than pure clathrate hydrates. Compound hydrate is a likely sink for many chemicals occurring on Titan's surface, including ethane, xenon, and other preferred clathrate formers
