50 Interesting Facts About Neon

Facts About Neon - Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air after nitrogen, oxygen, argon, and carbon dioxide were removed. Neon was the second of these three rare gases to be discovered and was immediately recognized as a new element of its bright red emission spectrum. The name neon is derived from the Greek word, νέον, the neuter singular form of νέος (neos), meaning 'new'. Neon is chemically inert, and no uncharged neon compounds are known. The compounds of neon currently known include ionic molecules, molecules held together by van der Waals forces, and clathrates.

• Neon can be liquefied and used as a cryogenic refrigerant.
• Trace amounts of neon are found in the Earth's atmosphere.
• Neon is the 5th most abundant element found in the universe.
• Its mass abundance in the universe is about one part per 750.
• There are only trace amounts of neon in the Earth’s atmosphere.
• Neon is in the noble gas element category on the periodic table.
• Neon has three stable isotopes and they are 20Ne, 21Ne and 22Ne.
• Neon is a group 18 chemical element, which is the noble gases group.
• It can be created commercially as the byproduct of liquefaction of air.
• Neon signs are made with neon gas and produce a bright reddish-orange light.
• The first verified public display of a neon sign was in 1910 by Georges Claude.
• Neon is a period 2 chemical element, which is the second row on the periodic table.
• While experimenting on liquid air, Sir William Ramsay and Morris Travers discovered neon in 1898.
• Neon was first isolated and discovered in 1898 by two British chemists, William Ramsay and Morris.
• Due to its rarity on Earth, neon is an expensive gas and can cost up to 55 times more than helium.
• Neon is the second lightest inert gas, as well as being the second lightest noble gas after helium.
• Neon has over forty times the refrigerating ability of liquid helium and three times that of liquid hydrogen.
• Neon's rarity makes it fairly expensive, making liquid neon about 55 times more expensive than liquid helium.
• Neon is left over, along with krypton and xenon, when nitrogen, oxygen, argon, and carbon dioxide are removed from air.
• Neon is the fifth most abundant chemical element in the universe, following behind hydrogen, helium, oxygen, and carbon.
• The concentration of neon in the atmosphere is about 1 part in 55,000, or 18.2 ppm by volume or 1 part in 79,000 of air by mass.
• The scientists had only recently discovered krypton prior to their discovery of neon, and would discover xenon shortly afterwards.
• Georges Claude began creating neon lighting in 1902, as he had surplus neon leftover as a by product of his air liquefaction company.
• In 1910, Georges Claude attempted to create interior home lighting using neon lights in vacuum tubes, but homeowners did not accept the idea due to their color.
• One of the more interesting facts about neon is that the light emitted from ionized neon can pass through water fog. This is why neon lighting is used in cold regions and for aircraft and airports.
• Even though it's rare and expensive on Earth, there is a fair amount of neon in the average home. If you could extract all the neon from a new home in the United States, you would have about 10 liters of the gas.
• Neon has a melting point of ‑248.59 C (‑415.46 F) and a boiling point of ‑246.08 C (‑410.94 F). Solid neon forms a crystal with a closely packed cubic structure. Because of its stable octet, the electronegativity and electron affinity of neon approaches zero.
• When low-pressure neon gas is electrified, it glows reddish-orange. This is the true color of neon lights. Other colors of lights are produced by coating the interior of the glass with phosphors. Other gases glow when excited. These are not neon signs even though many people commonly assume they are.
• Neon is a monatomic gas, so it is lighter (less dense) than air, which consists mostly of nitrogen (N2). If a balloon is filled with neon, it will rise. However, this will occur at a much slower rate than you would see with a helium balloon. As with helium, inhaling neon gas poses an asphyxiation risk if not enough oxygen is available to breathe.
• The name of the element comes from the Greek word "novum" or "neos," which means "new." British chemists Sir William Ramsay and Morris W. Travers discovered the element in 1898. Neon was discovered in a sample of liquid air. The gases that escaped were identified as nitrogen, oxygen, argon, and krypton. When the krypton was gone, the remaining gas was found to emit a bright red light when ionized. Ramsay's son suggested the name for the new element, neon.
• At room temperature and pressure, neon is an odorless, colorless, diamagnetic gas. It belongs to the noble gas element group and shares the property with other elements of that group of being nearly inert (not very reactive). In fact, there are no known stable neon compounds, even though some other noble gases have been found to form chemical bonds. A possible exception is solid neon clathrate hydrate, which may be formed from neon gas and water ice at a pressure of 0.35–0.48 GPa.
• Neon has many uses besides lighted signs. It is also used in helium-neon lasers, masers, vacuum tubes, lightning arresters, and high-voltage indicators. The liquid form of the element is a cryogenic refrigerant. Neon is 40 times more effective as a refrigerant than liquid helium and three times better than liquid hydrogen. Because of its high refrigeration capacity, liquid neon is used in cryonics to freeze corpses for preservation or for potential revival in the future. The liquid can cause immediate frostbite to exposed skin or mucous membranes.
