The element neon was discovered by Morris Travers and Sir William Ramsay. The chemists first isolated neon in 1898 by evaporating solid argon using low pressure. Neon was the third noble gas discovered by Ramsay and Travers, after argon and krypton.
After isolating krypton and argon from liquefying air, Ramsay and Travers recognized that another gas probably existed as well. It was given the name "neon" form the Greek word "neos," meaning "new, " and is the fourth most common element in the universe, comprising about 0.0018 percent of the Earth's atmosphere. It has an atomic number of 10 and the atomic symbol Ne.
Neon is most commonly used in advertising signs. The first neon sign was developed in 1902 by Georges Claude, an engineer. The neon creates light through the application of electricity to neon in a glass tube.
