The ions, Ne +, (Ne Ar) +, (Ne H) +, and ( HeNe +), have been observed from optical and mass spectrometric research. Neon is rare, found in the Earth's atmosphere at 1 part in 65,000 and industrially produced by cryogenic fractional distillation of liquified air. Neon is a monatomic gas at standard conditions. Neon ( Greek νέος meaning "new") was discovered by Scottish chemist William Ramsay and English chemist Morris Travers in 1898. 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 and helium are used to make a type of gas laser.The word "neon" is also used generically for these types of lights even though many other gases are used to produce different colors of light. The reddish-orange colour that neon emits in neon lights is widely used to make advertising signs and is also used in long tubular strips in car modification. All other colors (though still referred to as "neon") are created using a mercury vapor discharge which excites a phosphor via fluorescence. Neon is often used in signs and produces an unmistakable bright orange colored light. Neon has the most intense discharge at normal voltages and currents of all the rare gases. In most applications it is a less expensive refrigerant than helium. Neon is the second-lightest noble gas, glows reddish- 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). ![]() A colorless, nearly inert noble gas, neon gives a distinct reddish glow when used in vacuum discharge tubes and neon lamps and is found in air in trace amounts. Neon ( IPA: /ˈniːɒn/) is the chemical element in the periodic table that has the symbol Ne and atomic number 10. ![]()
