The story of the word

William Ramsay and Morris Travers boiled down liquefied air in 1898 and found three gases hiding in the last few drops. They named them for the discovery itself: krypton the hidden, neon the new, xenon the stranger. Superman's home planet borrowed the name from the chemistry, not the other way round.
