Neon: the essentials

Neon is a very inert element. Neon forms an unstable hydrate. In a vacuum discharge tube, neon glows reddish orange. Of all the rare gases, the discharge of neon is the most intense at ordinary voltages and currents. It is present in the atmosphere as 1 part in 65000.

Liquid neon has over 40 times more refrigerating capacity than liquid helium, and more than 3 times that of liquid hydrogen.

Neon: historical information

Neon was discovered by Sir William Ramsay, Morris W. Travers in 1898 at London, England. Origin of name: from the Greek word "neon" meaning "new".

Neon was discovered by Sir William Ramsay and Morris Travers in 1898 very shortly after their discovery of the element krypton. Both elements were discovered through work on liquid air. A little later they discovered xenon using similar methods.

Neon atoms have 10 electrons and the shell structure is 2.8. The ground state electronic configuration of neutral Neon is [He].2s2.2p6 and the term symbol of Neon is 1S0.

Isolation

Isolation: neon is present to a small extent in the atmosphere and is obtained as a byproduct from the liquefaction and separation of air. This would not normally be carried out in the laboratory and neon is available commercially in cylinders under pressure.

Neon isotopes Read more »

The three Neon isotopes are used for various purposes. Ne-22 is used for the production of the medical radioisotope Na-22. Ne-20 can be used for the production of F-18, although the route via O-18 is by far the most commonly used. Ne-21 has been used in Masers to study quantum physics.
