Xenon Fluoride Compound: Oxidation Number of Xenon
The Compound
Xenon fluoride (XeF) is a binary compound composed of xenon and fluorine. It is a colorless gas that can be synthesized by reacting xenon with fluorine gas at high temperatures and pressures.
Composition
The compound XeF contains 53.3% xenon by mass, with an atomic weight of 133. The remaining 46.7% is fluorine, which has an atomic weight of 19.
Oxidation Number
The oxidation number of an element is a measure of the number of electrons it has gained or lost in a chemical reaction. In the case of XeF, the oxidation number of xenon is +2.
Explanation
Xenon is a noble gas and has a full outer electron shell, making it very stable and unreactive. However, when it reacts with fluorine, xenon can lose its two outer electrons to form the compound XeF. In this compound, the oxidation number of fluorine is -1, as it gains one electron in the reaction. Therefore, to balance the charge, the oxidation number of xenon must be +2.
Conclusion
In conclusion, the compound XeF contains 53.3% xenon and 46.7% fluorine by mass. The oxidation number of xenon in this compound is +2, as it loses two electrons to form a bond with fluorine.
