When electrical energy is passed through a noble gas, light is emitted. Argan oil has a subtle, nutty flavor and a wide array of potential health benefits. Rather like a puzzle box containing exactly the right number of pieces, argon and its five cousins does not have any subatomic shortages that need to be amended by donations from other elements, and it doesn't have any extras floating around to donate in turn. It is not found in any compounds. Formerly with ScienceBlogs.com and the editor of "Run Strong," he has written for Runner's World, Men's Fitness, Competitor, and a variety of other publications. The real-world implications of this is that noble gases have no shareable electrons. When argon has been inhaled, standard respiratory support, including oxygenation by mask, may be required to being blood oxygen levels back to normal; getting the affected person out of the argon-rich environment is of course necessary as well. If someone asked you to name the three most abundant gases in Earth's atmosphere, you might choose, in some order, oxygen, carbon dioxide and nitrogen. Argon will not react with most other substances (though it will at extremely high temperatures). The following uses for argon are gathered from a number of sources as well as from anecdotal comments. This means that these elements – the only elements to exist as gases at room temperature, the others all being liquids or solids – have what is called a high ionization energy. Argon is used in welding, which is a process in which two metals are joined to each other. It's important to get well-versed with the uses of argon (and its properties that make it one of the most useful elements on the planet), if we are to understand how important it is for us.
