Is neon a connection


properties

Neon was discovered by William Ramsay and Morris Travers in 1898. It is the second brightest noble gas, glows reddish-orange in vacuum discharge tubes and in neon lamps and has a cooling capacity 40 times higher than liquid helium and three times higher than that of liquid hydrogen (per unit volume). For most applications it is a cheaper coolant than helium. Neon has the most intense discharge capacity at normal voltages and currents of all rare gases.
Although neon is the fourth most abundant element in the universe, the earth's atmosphere contains only 0.0018% neon.
The reddish-orange color that neon emits is commonly used for advertisement lighting to make up advertising signs. Neon is also used for the type of lights where many other gases are used to produce different color variations. Other uses of neon include high voltage displays, lightning rods, wave gauges and television tubes.
Neon and helium are also used in the Ne / He laser. Liquefied neon is used commercially as an economical refrigerant refrigerant.

Neon usually occurs in a gas form (mostly in molecules) that contain a single neon atom. Neon is a rare gas found as 1 in 65,000 particles in the Earth's atmosphere. It is produced by air subcooling and subsequent fractional distillation of this cryogenic liquid.

Although too inert an element for most practical purposes, neon can make an extraordinary combination with fluorine in the laboratory. It is not known for sure whether this neon compound or other Ne compounds occur naturally. But there are indications that it might be possible.
The ions Ne +, (NeAr) +, (NeH) + and (HeNe) + could also be observed in optical and mass spectrometric research. In addition, neon forms an unstable hydrate.

Neon has three persistent isotopes: Ne-20 (90.48%), Ne-21 (0.27%), and Ne-22 (9.25%). Ne-21 and Ne-22 arise from nuclear reactions and their transformations and changes are well understood. In contrast, it is known that Ne-20 does not result from nuclear reactions. The causes of the formation and mass change have been hotly debated. The main nuclear reactions that give rise to neon isotopes are neutron emission and alpha decay reactions of Mg-24 and Mg-25. These produce Ne-21 and Ne-22. The alpha particles are formed by uranium as a result of the decay chains, while the neutrons are mostly produced by secondary reactions of the alpha particles. The net yield tends to be lower Ne-20 / Ne-22 and higher Ne-21 / Ne-22 ratios, which are observed in uranium-rich rocks such as granites. Isotopic analysis of the rocks examined has shown a cosmogenic production of Ne-21. This isotope is produced by nuclear fission reactions of Mg, Na, Si and Al. By analyzing all three isotopes, the knowledge of igneous neon and the neon generated by the nucleus can be used to find out the cosmogenic component. In this way, neon can serve as a useful tool for cosmic dating of rocks or meteorites on the earth's surface.

Similar to xenon, traces of neo (enriched with Ne-20) and the nucleogenic Ne-21 in relation to Ne-22 were observed in samples of volcanic gases.
The isotopic neon portion of these jacketed samples represents a non-atmospheric source of the neon. The Ne-20 enrichment components were attributed to exotic original rare gas components of the earth and possibly represented solar neon. Elevated amounts of Ne-20 were also found in the diamonds, which in turn is one suggests a possible supply of solar neon in the earth.

Health effects of neon

This gas is inert and belongs to the nitrogen gases. Inhalations of very high concentrations can cause nausea, vomiting, unconsciousness and death.
Death can occur indirectly as a cause of impaired consciousness, nausea or unconsciousness, since in these states it is impossible to rescue oneself from life-threatening situations. At low oxygen concentrations, unconsciousness and death can occur within seconds (without prior warning).
The symptoms of suffocation are proportional to the decrease in the partial pressure of oxygen in the air. Only when the oxygen content of the inhaled air has dropped to 75% of its original concentration in the air (75% from 21%) can noticeable symptoms develop. This requires the presence of nitrogen gas in a concentration of 33% in the air-gas mixture. If the asphyxiant reaches a concentration of 50% permanent damage can result. A concentration of 75% of the nitrogen gas in the air is fatal after a few minutes.

The first symptoms that occur from nitrogen gas are shortness of breath and a lack of air. The ability to concentrate is reduced and the coordination of movements is restricted.
Judgment is also restricted and all sensations are suppressed. Often there is emotional instability and rapid fatigue. As the attack progresses, nausea and vomiting, loss of consciousness, and ultimately convulsions, deep coma, and death may occur.

Environmental effects of neon

Neon is a rare atmospheric gas and is therefore non-toxic and chemically inert.

There is no known ecological damage caused by this element.
