In July 1898, British scientists W. Ramsay and Morris William Travers fractionated liquid air and discovered a new heavy gaseous element with a low boiling point in the last part of the distillation, excluding krypton (Kr) and neon (Ne). They named it xenon after the Greek word xenos (foreign). …

In May 1898, British scientists W. Ramsay and Morris William Travers discovered a new heavy gas element in the liquid remaining after distilling liquid air to extract argon (Ar), and named it krypton after the Greek word kryptos (hidden one). Its content in air is 1.1×10 ^-4 % by volume. …
