Xenon: The Foreigner Gas

Xenon, a noble gas with the symbol Xe and atomic number 54, gets its name from the Greek word "xenos," meaning "foreigner" or "stranger." This moniker was given due to its unusual and unexpected discovery in 1898 by Scottish chemist William Ramsay and his colleague Morris Travers.
