Neon atomic symbol


Introduction to Neon:

Neon's discovery happened in 1898 by Ramsay & Travers. It is one of the rarest gases present in atmosphere to the extent of 1 part in 65,000 in the air. It is first obtained by air liquefaction and then through fractional distillation for separation of other gases. It is part of Group 18 elements in periodic table.

Properties and application of Neon:

Neon is a compound mixture of 3 isotopes. Apart from this, there are six other unstable isotopes. Though Neon is an inert element, it is found to have produced a compound in reaction with fluorine. Some of the ions of Neon are used in the study of mass spectroscopy and optical spectroscopy. It is used as a refrigeration compound in place of Helium as it costs less. At normal conditions of voltage & current, Neon displays intense behavior compared to all other inert gases.
Neon has an Atomic Mass of 20.1797 amu. Its melting point is supposed to be -248 °C.  Its boiling point is considered-246 °C.  Its crystal structure is in the form of a face-centered cube. Its density is supposed to be 0.9002 g/cm3
Neon is used in signboards as it appears very bright and reddish orange in color. Neon lights are used during foggy seasons as it can penetrate fog.  It is used in vacuum tubes, television tubes and in lasers. Liquid neon is used as a cryogenic refrigerant. But liquid neon is very expensive compared to liquid helium.
Neon belongs to p-block of noble gases in the periodic table. It is supposed to be the most inert element. It is believed by scientists that neon reacts with fluorine to produce different compounds. On reaction with water, neon produces unstable hydrate. Neon is produced in huge quantities during volcanic eruptions.  It combines with helium  gas to produce neon-helium lasers.

Conclusion:


Neon being the fifth most abundant element has variety of applications. It is also the second lightest gas and inert in nature which helps us in various applications.
