The chemical element with the symbol 'Xe' is xenon. Xenon is a noble gas, found in Group 18 of the periodic table. It is colorless, odorless, and highly unreactive under normal conditions, which is characteristic of noble gases. Xenon occurs in trace amounts in the Earth's atmosphere and can be isolated through fractional distillation of air. Due to its properties, xenon is used in various applications, including high-intensity discharge lamps, flash lamps, and as a general anesthetic in some medical procedures. Its unique characteristics make it an interesting subject in chemistry.
