![]() If a balloon is filled with neon, it will rise. Neon is a monatomic gas, so it is lighter (less dense) than air, which consists mostly of nitrogen (N2).These are not neon signs even though many people commonly assume they are. Other colors of lights are produced by coating the interior of the glass with phosphors. When low-pressure neon gas is electrified, it glows reddish-orange.Because of its stable octet, the electronegativity and electron affinity of neon approaches zero. Solid neon forms a crystal with a closely packed cubic structure. ![]() ![]() If you could extract all the neon from a new home in the United States, you would have about 10 liters of the gas. Even though it's rare and expensive on Earth, there is a fair amount of neon in the average home.This is why neon lighting is used in cold regions and for aircraft and airports. One of the more interesting facts about neon is that the light emitted from ionized neon can pass through water fog.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.Georges Claude began creating neon lighting in 1902, as he had surplus neon leftover as a by product of his air liquefaction company.The scientists had only recently discovered krypton prior to their discovery of neon, and would discover xenon shortly afterwards.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.Neon is the fifth most abundant chemical element in the universe, following behind hydrogen, helium, oxygen, and carbon.Neon is left over, along with krypton and xenon, when nitrogen, oxygen, argon, and carbon dioxide are removed from air.Neon's rarity makes it fairly expensive, making liquid neon about 55 times more expensive than liquid helium.Neon has over forty times the refrigerating ability of liquid helium and three times that of liquid hydrogen.Neon is the second lightest inert gas, as well as being the second lightest noble gas after helium.Due to its rarity on Earth, neon is an expensive gas and can cost up to 55 times more than helium.Neon was first isolated and discovered in 1898 by two British chemists, William Ramsay and Morris.While experimenting on liquid air, Sir William Ramsay and Morris Travers discovered neon in 1898.Neon is a period 2 chemical element, which is the second row on the periodic table.The first verified public display of a neon sign was in 1910 by Georges Claude.Neon signs are made with neon gas and produce a bright reddish-orange light.It can be created commercially as the byproduct of liquefaction of air.Neon is a group 18 chemical element, which is the noble gases group.Neon has three stable isotopes and they are 20Ne, 21Ne and 22Ne.Neon is in the noble gas element category on the periodic table.There are only trace amounts of neon in the Earth’s atmosphere.Its mass abundance in the universe is about one part per 750.Neon is the 5th most abundant element found in the universe. ![]()
