Neon is a chemical element that makes up about 1 part per 65,000 in Earth's atmosphere. The British chemists Sir William Ramsay and Morris W. Travers discovered the element in the atmosphere while they were studying liquid air in 1898. Ramsay had predicted the existence of this gas in 1897. Ramsay and Travers named the gas neon, for the Greek word that means new.
