Neon is abundant in universal terms but is relatively rare in the Earth''s atmosphere where it is found at 1 part in 65,000 (by volume) or 1 part in 83,000 by mass. It was discovered in 1898, by the Scottish chemist William Ramsay and English chemist Morris W. Travers. Ramsay chilled a sample of the atmosphere until it became a liquid, then warmed the liquid and captured the gases as they boiled off.
