Xenon was discovered by Ramsay and Travers in 1898. Xenon is rare, present in the air in minute quantities. It can be found in the gases from certain mineral springs, and is commercially produced by separating it from liquid air. Xenon is used in making high intensity light sources such as stroboscopic lamps and bactericidal lamps. [LM] {RW}
