INTRODUCTION
Neon is a very light and least reactive gas and is difficult to handle in the laboratory due to its ability to diffuse through glass,rubber,plastic materials and some metals.
In the past few decades chemists have managed to induce several of the noble gases to form compounds with other extremely reactive elements, such as fluorine, but neon and helium have so far resisted these efforts.

ECONOMIC IMPORTANCE
* Small amounts of neon are used in discharge tubes to give the familiar reddish orange glow of 'neon' used in signs.
* Neon lights are also used in aerodrome beacons as they have a high power of fog penetration.
* Liquid neon is used as a cryogenic refrigerant and has over 40 times more refrigerating capacity per unit volume than liquid helium.
* It is also used in television tubes, gas lasers, and high-voltage indicators.
