Neon ( that has the symbol '''Ne''' and Atomic Number 10. A very common element in the universe, it is rare on Earth. A colorless, Inert Noble Gas under standard conditions, neon gives a distinct reddish glow when used in vacuum discharge tubes and Neon Lamp s. It is commercially extracted from air, in which it is found in trace amounts. NOTABLE CHARACTERISTICS Neon is the second-lightest Noble Gas , glows Red dish- Orange in a Vacuum Discharge Tube and has over 40 times the refrigerating capacity of liquid Helium and three times that of liquid Hydrogen (on a per unit volume basis).1 In most applications it is a less expensive Refrigerant than helium.2 Neon plasma has the most intense light discharge at normal voltages and currents of all the rare gases. The average color of this light to the human eye is red-orange; it contains a strong green line which is hidden, unless the visual components are dispersed by a spectroscope.3 APPLICATIONS and produces an unmistakable bright orange colored light. All other colors (though still referred to as "neon") are created using a mercury vapor discharge which excites a Phosphor via Fluorescence , or by the other Noble Gases .]] The reddish-orange color that neon emits in Neon Light s is widely used to make advertising Signs and is used in long tubular strips in car modification. The word "neon" is used generically for these types of lights even though many other gases are used to produce different colors of light. Neon may also be used in Vacuum Tube s, high-voltage indicators, Lightning arrestors, wave meter tubes, Television tubes, and Helium-neon Laser s. Liquefied neon is commercially used as a Cryogenic Refrigerant in applications not requiring the lower temperature range attainable with more expensive liquid helium refrigeration. Neon's , 2007 .
