Follow the appropriate hyperlinks for literature references and definitions of each type of radius. There are several other ways ways to define radius for atoms and ions. It is not always easy to make sensible comparisons between the elements however as some bonds are quite short because of multiple bonding (for instance the O=O distance in O 2 is short because of the the double bond connecting the two atoms. Removal of argon from water is insignificant.One measure of size is the element-element distance within the element. Which water purification technologies can be applied to remove argon from water? Depending on exposure time, exposure to argon may lead to nausea and sleepiness, followed by breathlessness, unconsciousness, and possible death by asphyxiation. The only health effect that may be of importance is argon accumulation in air that is breathed in, leading to oxygen deprivation and asphyxiation. Health effects from argon present in drinking water are not expected. The element is not a dietary requirement. What are the health effects of argon in water?Īrgon is present in the human body in trace amounts. Argon is non-water hazardous and no known environmental effects have occurred.Īrgon naturally has three stable isotopes, and we now know of nine instable isotopes. Diazotrophs, bacteria that absorb nitrogen and convert it to ammonia, may absorb argon, but they cannot apply it. What are the environmental effects of argon in water?Īrgon does not have any biological use. Argon is a by-product of fractioned distillation for hydrogen production.ĭespite all the above-mentioned processes, contamination of water by commercially applied argon is virtually impossible. This is achieved by decay of solid 40K with a half-time of 1.3 million years to gaseous 40Ar that cannot escape from solids, merely during a melting process. The argon method or potassium-argon method is applied in geology to date solidification time of volcanic materials. Argon may be a useful marker, because it does not react with any present product, and during surface treatment it may be a useful carrier that does not react with target material. Another popular application are argon laser for eye correction and tumor removal.

Argon is applied in tyres of luxury cars to protect rubber and prevent noise emissions at high speed. It may also be applied as a protective coating from temperature change, for example as insulation in the interspace of double-glazing. In atomic research argon is applied to protect other elements from unwanted effects.

It is applied as insulation gas when air is trapped to protect heated metal from oxidation, for example during aluminium or titanium production. The larger part of argon production is carried out in steel industries. In fluorescent lamps it aids the starting mechanism. This may be of significance for electrical lighting. Argon may than be applied as a protective sphere, because it is very unreactive. It is applied commercially for different purposes and is extracted from fluid air by 750,000 tons annually. Argon does not remain dissolved in water, at least not in higher than normal concentrations.Īrgon occurs in a number of potassium minerals by radioactive decay of the 40K isotope. Clathrates contain argon and release the element upon dissolution. Consequently, argon does not react with water.Īrgon has a water solubility of 62 mg/L at 20 oC and pressure = 1 bar. One succeeded in producing only one argon compound that was very instable, under extremely low temperatures. It does not even react at high temperatures or under any other special conditions. In what way and in what form does argon react with water?Īrgon is a noble gas and it does not react with any other element.
