Neon: the essentials

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.

Neon: description  

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: history

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: isotopes

Isotope abundances of neon
Isotope abundances of neon with the most intense signal set to 100%.

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.

Neon: 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.
