About Xenon
Xenon is a noble gas with atomic number 54 that is relatively unreactive but can form compounds with strongly electronegative elements. Xenon gas is used in specialized lamps and ion propulsion systems. Xenon difluoride has a distinct chemical role as an etchant for silicon, demonstrating that useful noble gas compounds can exist despite the element's low reactivity.
