All About Argon

Argon is an inert gas that is both colorless and odorless and that is grouped in the Noble gases.  Argon acquired its name from the Greek word for “lazy,” as a result of its propensity to have little reactivity when it comes to forming compounds. This gas is most frequently utilized in welding and additionally utilized regularly in fluorescent lighting.

According to Chemicool, a vast abundance of the argon on Earth is the isotope argon-40, which is generated from the radioactive decay of potassium-40. Contrarily, argon in space is developed from stars, that takes place when two hydrogen nuclei fuse with silicon-32, resulting in the isotope argon-36.

Argon, while inert, is not limited. Contrarily, about 0.9 percent of the earth’s atmosphere is made up of this gas. According to calculations by Chemicool, this indicates that there are about 65 million metric tons of argon in the atmosphere, and this number continues to grow due to the decay of potassium-40.

To detail a few of its characteristics, Argon (Ar) has the atomic number 18 and an atomic weight of 39.948. At room temperature, Argon is a gas.

The first discovery of argon occurred in in 1785 when Henry Cavendish, a British scientist, identified a segment of air that seemed especially inert. Initially, Cavendish was unable to tell what this air was. It was not until over one hundred years later in 1894 that two men, Lord Rayleigh and Scottish chemist William Ramsey could accurately classify and describe the gas, which subsequently earned them the Nobel Prize in Chemistry for this discovery. Additionally, studying argon’s elemental properties also guided Ramsey to discover helium, neon, krypton, and xenon.

Because of its inertness, argon is frequently used in industrial tasks that necessitate for a non-reactive atmosphere. Additionally, argon serves as an effective insulator, which has led to it commonly being used to warm divers while deep-sea diving. Argon is likewise used in historical preservation and is pumped around significant documents such as the Magna Carta and a world map from 1507. Unlike oxygen and similar reactive elements, the argon helps protect the paper and ink on these delicate documents.

Additionally, there are several less frequently discussed uses for argon. For example, argon is used in neon lights that shine blue, since neon itself emanates an orange-red color. In addition, argon is regularly employed in laser technology, including the lasers used in vision correction surgeries such as LASIK and PRK procedures. Argon has even been employed to uncover contaminated groundwater in certain areas of the United States. In this instance, argon and other noble gases were injected into wells where they infused with methane.

Presently, there is a sizeable amount of research being performed on argon to discover additional potential uses of the gas. For example, it is right now being studied as a potential alternative to the costly gas xenon and its part in treatment of brain injuries. Additionally, a few experiments have found that argon could at some point be utilized to limit brain injuries that have happened a result of oxygen deprivation or other traumatic incidents. A review published in the Medical Gas Research journal found that in several circumstances, treating injuries with argon considerably decreased the death of brain cells. Researchers are not yet clear about why argon impacts brain cells in this manner. Until now, argon has been employed in this research by either being applied directly to cells in a culture dish or delivered mixed with oxygen in a facemask for animal studies. As argon research progresses, it is turning increasingly likely that human trials will start eventually. However, there seem to be risks associated with argon treatment, and because of this more research must be carried out until this practice can be employed.
