​ Ne a.k.a NEON​ Neon (meaning "new one") was discovered in 1898 by the British chemists William Ramsay and Morris Travers in London. Neon was discovered when Ramsay chilled a sample of the atmosphere until it became a liquid, then warmed the liquid and captured the gases as they boiled off. The three gases that boiled off were krypton (A colorless, odorless, tasteless noble gas), xenon (A colorless, heavy, odorless noble gas), and neon.
 * Neon** is the chemical element that has the symbol **Ne** and atomic number 10. Although a very common element in the universe, it is rare on Earth. A colorless,noble gas*, neon gives a distinct dark orangie glow when used in discharge tubes (The **Geissler tube** is a glass tube for demonstrating the principles of electrical glow discharge), neon lamps and advertising signs. It is commercially extracted from air, in which it is found in trace amounts.

In 1910, French engineer Georges Claude made a lamp from neon gas. In 1912, Claude's associate began selling neon tubes as advertising signs. They were introduced to U.S. in 1923. The glow and bright colour made neon advertising completely different from the competition.

Neon is the second-lightest noble gas. According to recent studies, neon is the least reactive noble gas and the least reactive of all elements.It has over 40 times the refrigerating capacity of liquid. In most applications it is a less expensive than helium.

Neon is actually plentiful on a universal scale: the fifth most abundant chemical element in the universe by mass, after hydrogen, helium, oxygen, and carbon. Its relativly rare on Earth, like helium, is due to its light wieght, which tend to keep it from being trapped in gas which resulted in the formation of smaller and warmer solid planets like Earth.

The six noble gases that occur naturally are helium(He), neon(Ne), argon(Ar), krypton (Kr) and xenon(Xe). Xenon is used in flash lamps and arc lamps Krypton, can be used in lighting and photography
 * The **noble gases** (often mistakenly referred to as **inert gasses**) are a group of chemical element with very similar properties: under normal conditions, they are all odorless, colorless,monatomic(single atom) gases, with a very low chemical reactivity.
