Xenon, with the chemical symbol Xe and atomic number 54, is a noble gas that was first discovered in 1898 by British scientists Sir William Ramsay and Morris Travers. They isolated it from residues obtained during the distillation of liquid air. The name "xenon" is derived from the Greek word "xenos," meaning "foreign" or "strange."

On Earth, xenon is an extremely rare element, constituting only about 0.000009 ppm of the Earth's atmosphere. It is primarily formed through the radioactive decay of heavy elements and is obtained during the extraction of air gases.

Xenon finds fascinating applications in high technology. It is used in certain types of gas discharge lamps, such as flash lamps and neon signs. In medicine, xenon serves as a contrast agent in imaging techniques like magnetic resonance imaging (MRI). Future applications of xenon could be in the field of space exploration and as a propellant for ion thrusters.
