An oxide ( / ksad /) is a chemical compound that contains at least one oxygen atom and one other element [1] in its chemical formula. Initially, it was believed that noble gases are incapable of forming compounds as they have complete octets, and thus they possess very high stability. Like KrF+, the XeF+ cation behaves as a electron pair acceptor toward nitrogen Lewis bases, but because XeF+ is not as powerful an oxidant as KrF+, the range of ligands that can be coordinated to XeF+ is more extensive. Updates? Like most covalent inorganic fluorides it is moisture-sensitive. Hence, much of currently known xenon chemistry involves its fluorides and oxofluorides in their reactions with strong Lewis acid acceptors and fluoride-ion donors to form a variety of fluoro- and oxofluorocations and anions, respectively. However, xenon is a heavier noble gas and it consists of more shells. The innermost electrons of xenon show a shielding effect on the valence electrons, and thus the outermost electrons do not experience much pull from the nucleus. Among the first xenon-nitrogen bonded compounds to be prepared were FXe[N(SO2F)2] and Xe[N(SO2F)2]2. Shape of Xenon dioxide can be defined by studying its Lewis structure in detail.

It is synthesized at 0 C by hydrolysis of xenon tetrafluoride in aqueous sulfuric acid: [2] For example, xenon-135 (9.2-hour half-life) is produced by uranium fission in nuclear reactors, where it is troublesome because it absorbs fission-producing neutrons. When xenon tetrafluoride undergoes hydrolysis, xenon hydrofluoric acid and oxygen are formed from which xenon dioxide is recovered on evaporation.
