- Argon is a chemical element, a noble gas, and the most abundant and industrially used of the inert gases123. It has the chemical symbol Ar and the atomic number 18124. It is colorless, odorless, tasteless, and nontoxic12435. It constitutes about 1% of air and is obtained by distillation of liquid air23. It is used in fluorescent lights, welding, annealing, and rolling metals and alloys43. It can displace oxygenated air in enclosed spaces and cause asphyxiation5.Learn more:✕This summary was generated using AI based on multiple online sources.

Argon (Ar) is a noble gas that comprises 0.93 % of the earth’s atmosphere. Argon provides an inert and clean environment free from nitrogen and oxygen for annealing and rolling metals and alloys.www.lindedirect.com/resources/gases/argonArgon is an inert, colorless and odorless element — one of the Noble gases. Used in fluorescent lights and in welding, this element gets its name from the Greek word for "lazy," an homage to how little it reacts to form compounds.www.livescience.com/29023-argon.htmlArgon is a colorless, flavorless, odorless noble gas. Unlike some other gases, it remains colorless even in liquid and solid form. It is nonflammable and nontoxic. However, since argon is 38% more dense than air, it present an asphyxiation risk because it can displace oxygenated air in enclosed spaces.www.thoughtco.com/interesting-argon-element-fac…
