Neon


History

Discovered by Ramsay and Travers in 1898. Neon is a rare gaseous element present in the atmosphere to the extent of 1 part in 65,000 of air. It is obtained by liquefaction of air and separated from the other gases by fractional distillation.

Isotopes

Natural neon is a mixture of three isotopes. Six other unstable isotopes are known.

Compounds

Neon is a very inert element, however, it has been reported to form a compound with fluorine. It is still questionable if true compounds of neon exist, but evidence is mounting in favor of their existence. The ions, Ne+, (NeAr)+, (NeH)+, and (HeNe+) are known from optical and mass spectrometric studies. Neon also forms an unstable hydrate.

Properties

In a vacuum discharge tube, neon glows reddish orange.

It has over 40 times more refrigerating capacity per unit volume than liquid helium and more than three times that of liquid hydrogen. It is compact, inert, and is less expensive than helium when it meets refrigeration requirements.

Of all the rare gases, the discharge of neon is the most intense at ordinary voltages and currents.

Uses

Although neon advertising signs account for the bulk of its use, neon also functions in high-voltage indicators, lightning arrestors, wave meter tubes, and TV tubes. Neon and helium are used in making gas lasers. Liquid neon is now commercially available and is finding important application as an economical cryogenic refrigerant.

Neon Signs

Neon signs are great advertising for any business. They work well for retail settings such as game rooms, restaurants, diners, manufacturing units, pubs and lounges, fraternity lounges, and many other establishments.
The first set of neon signs was sold by a French company named Neon Claude to a Packard car dealership in Los Angeles in 1923, for a sum of $24,000.These “liquid fire” tubes glowed in the night as well as broad daylight and soon became popular. Since then, the neon technology has evolved tenfold, and the signs are more popular than ever today.
Not all signs are made of neon, since the neon gas only produces the color red. After the initial discovery of neon-emitting red light, other colors were discovered using mercury, carbon dioxide, and phosphor. Today, it is possible to produce more than 150 colors using these gases. Neon tubes are actually positive-charge-filled lamps.
Every neon sign made is handcrafted; despite the advancement in technology, the manufacturing of a sign just cannot be done by a machine. According to the design wanted, the artisan heats a glass tube into a pliable shape and then moulds the design and lettering as per the requirements. During this process of continuous heating and bending, air is let into the tube to maintain its hollow shape. After the designing is done, the tubes are vacuumed out using a suction pump, after which an inert gas is let into the tube—this gas determines the color of the neon sign. The gas-filled tube glows when current is passed through it ionizing the gas, thus causing it to glow.
