![]() Neon is used not only in advertising signs but also for vacuum tubes, television tubes, plasma tubes, and helium-neon lasers, high-voltage indicators. The neon light is for this reason used by and is very important to airports in cold areas. Whilst other lights can not pass through fog Neon light cannot be obscured by it. Signs of any other color are not true neon and are made up of other noble gasses or are a form of colored fluorescent lighting. True Neon actually only glows a reddish-orange in a vacuum. Many Signs We Think Of as Neon Really Aren't!! However, in the Earth's atmosphere Neon is a particularly rare gas making up 0.0018% of the atmosphere. It is the most abundant gas after hydrogen, helium, oxygen, and carbon. Neon is the fifth most abundant element in the Universe. In the average home in the USA, there are approximately 10 liters of Neon Gas present! It is Both an Abundant Element in the Universe and Rare Therefore do not expect to look up to a Neon sky at night time. However, without an electrical current, neon remains colorless. Neon is created during the alpha process of stars, which is when helium and oxygen are fused together.

Travers had made a very important discovery and probably didn't know how important Neon would become. These three gases are left over when nitrogen, oxygen, argon, and carbon dioxide are removed from air. ![]() During this research and experimentation William Ramsay and Morris Travers discovered not one, but three new gases: krypton, neon, and xenon. This was the method they employed to discover new elements. They had the knowledge that there must be elements on the periodic table between helium and argon, so they conducted research about liquid air.Ĭooling air until it became a liquid, they then warmed the liquid and collected the gases that boiled off. In 1898 the Neon gas was discovered at University College London by two British scientists, Sir William Ramsay and Morris W. However, we have in the following compiled some fun facts about true neon gas that is used in traditional neon signs. We are all about Neon Signs here at Neon Mamma, the new-age LED version that is. ![]()
