4/16/2023 0 Comments Neon atomic number![]() ![]() It is now known, however, that several of these elements are quite abundant on Earth and in the rest of the universe, so the designation rare is misleading. When the members of the group were discovered and identified, they were thought to be exceedingly rare, as well as chemically inert, and therefore were called the rare or inert gases. Their electronic structures and the finding that some of them do indeed form compounds has led to the more appropriate designation, Group 18. They traditionally have been labeled Group 0 in the periodic table because for decades after their discovery it was believed that they could not bond to other atoms that is, that their atoms could not combine with those of other elements to form chemical compounds. The noble gases are colourless, odourless, tasteless, nonflammable gases. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table.

In addition, neon lighting is used by artists. They are also used as Nixie tubes which are electronic devices to display numerals or other info using glow discharge. Neon lamps (or glow lamps) are used as indicators, voltage testers, microwave and millimeter-wave detectors, and night-lights. Liquid neon is commonly used as a cryogenic refrigerant. Neon (Ne), a chemical element and a tasteless, odorless, colorless inert gas of Group 18, is especially used for electric signs (neon signs), fluorescent lighting, high-voltage indicators, television tubes and wave meter tubes. Liquid neon is very good refrigerant widely used for preserving low temperatures in various kinds of industries. Neon turns bright red when charged with the electric current. Neon is an element that is important for producing some types of lasers, electrical indicators, equipment for sports (especially water-sports), and so on. It is extensively used for producing so called neon lights, primarily for decorative and advertising purposes. In very small amounts, neon can be found in air, especially in northern parts of the atmosphere of our planet. With the name which comes from a Greek word meaning new, neon is a noble gas that has ho odor and color, non-toxic and biologically not very important. ![]()
