What is Neon used for?
Apr 01, †Ј The element is also used in helium neon lasers, television tubes and wave meter tubes. It is also used in lightning arresters. This is used to shield electrical equipment from lightning. There are also high voltage indicators and vacuum tubes that employ it. Mar 17, †Ј Neon (Ne), chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps. Colourless, odourless, tasteless, and lighter than air, neon gas occurs in minute quantities in EarthТs atmosphere and trapped within the rocks of EarthТs crust.

This element is more abundant uee the cosmos than on What do we use the element neon for. When under low pressureit emits a bright orange-red light if an electrical current is passed through it. This property is utilized in neon signs which first became familiar in the sin some fluorescent and gaseous conduction lamps, and in high-voltage testers.
Travers as a whxt of the most volatile fraction of liquefied crude argon obtained from air. It was immediately recognized as a new element by its unique glow when electrically stimulated.
Its only commercial source is the atmosphere, in which it is 18 parts per million by volume. Elemwnt is isolated from this cold, gaseous mixture by bringing it into contact with activated charcoalwhich adsorbs the neon and hydrogen; removal of hydrogen is effected dor adding enough oxygen to convert it all to water, which, along with any surplus oxygen, condenses upon cooling. Processing whatt, pounds of liquid air will produce one pound of hse.
No stable chemical compounds of neon have been observed. Molecules of the element consist usd single atoms. Natural how to clean a gas boiler is a mixture of three stable isotopes : neon Neon was the first element shown to consist of more than one stable isotope.
Inwhah of the technique of mass spectrometry revealed the existence of neon and neon The himalayan poppies blue how to grow stable isotope, neon was detected later.
Twelve radioactive isotopes of neon also have been identified. Additional Info. More About Contributors Article History. Home Science Chemistry Neon chemical element. Print Cite verified Cite.

Quick Facts about Neon
Neon, the second-lightest inert gas, is used in advertising signs, fluorescent lamps, TV tubes, and lightning arrestors. Read on to understand about the quick facts and uses of neon element. The element neon is represented by the symbol СNeТ. It is an inert gas with atomic number Apr 24, †Ј This is why neon is commonly used in glow lamps and advertising signages. As a noble gas, Neon has no color, odor, and/or taste. This chemical element can only be commercially sourced through the air in the atmosphere. Neon was said to be discovered back in by chemists Sir William Ramsay of Scotland and Morris M. Travers of England.
Neon is not very common on Earth, but is one of the most abundant in the universe. Even if that is the case, the element is utilized in many ways by people. Its symbol is Ne and the atomic number is Common Uses of Neon. Its most common application is in advertisement.
Ne generates a bright reddish orange color. Neon lights refer to various colors and lights. However, neon lights come from other gases and not necessarily neon. The element is also used in helium neon lasers, television tubes and wave meter tubes. It is also used in lightning arresters. This is used to shield electrical equipment from lightning.
There are also high voltage indicators and vacuum tubes that employ it. Ne discharges electricity at regular voltages and currents. Other inert gases do not. The orange red light appears when Ne gas is placed in a tube and current goes through it. Ne gas only produces orange red; other gases are used to produce other colors. The Ne gas discharge is applied in neon glow lamps, fluorescent lamps and other lighting systems.
Most of these lamps can function without using high voltages. Neon signs use high voltages though, up to 2 kv at least.
Because of the way it is used, Ne is sometimes called fill gas. Neon light cannot be obscured by fog whereas other lights are affected. Adding traces of mercury into Ne turns the orange red color to vivid blue. Changing the composition of mercury and neon produces other lights, colors and shades. It is these colors that are used for landscaping and interior design.
Ne is valued as a lighting system because it is usable in cold places. That is also the reason why the element is used in aircraft beacons and aircraft. Ne can also be used as a cryogenic refrigerant. Research shows that Ne per unit volume of liquid has 40x more capacity than liquid helium. Neon in a liquid state has three times more capacity than liquid hydrogen. The element is formed out of unstable hydrate. A few gases have discharges, but none are as powerful as that of neon.
The element has three stable isotopes. Their weights are 22, 21 and There are also a dozen radioactive isotopes which are unstable. In room temperature it is gaseous and colorless. Its properties and lightness are the reasons why it is so rare. Only 0. The neon used in industries is taken from the air. Its standard state is gas at K. It belongs to 18 in the periodic table. They discovered neon shortly after uncovering krypton.
On a universal scale, it is the fifth most common. As stated earlier, the reason for its rarity is chemical inertness and high vapor pressure. This keeps the element from being ensnared in dust clouds and condensed gas. By comparison, the molecules in oxygen and nitrogen are much heavier.
Stuffing a balloon with neon will cause it to rise. But it will be slower compared to a balloon with helium. The Galileo spacecraft discovered that neon can be found in Jupiter.
But like on Earth, the amount is reduced compared with other elements. The basic process used to create them is the same. Neon or other gases are placed in bulbs or glass tubes. The process was discovered by the French engineer Georges Claude. He demonstrated neon tube lighting from December 3Ч18, at the Paris Motor Show. From the s to the s, its usage became widespread in Europe. It also became a hit in the US during that same time. By , almost every city in the US was making use of this technology.
Neon signs and ads became especially popular in Times Square in New York. Neon lighting can also come in the form of miniature neon glow lamp. This technology was developed in Unlike neon tubes, these are much shorter.
However, the intensity is less. Eventually, the neon glow lamp led to the development of modern TVs and displays.
Fluorescent lighting came nearly 25 years later. While there are many uses of neon, they are not as many as those of other elements. The reason is money. Neon costs 50x more than helium to produce.
