Description
An inert, colorless, odorless, gaseous element. Argon has an abundance of 0.935% in the earth's atmosphere. It was discovered in 1894 by Lord Rayleigh and Sir William Ramsay. Argon is inert but will form compounds with highly electronegative elements such as Oxygen and Fluorine. It is used as a filler in incandescent lightbulbs and neon-type bulbs where it produces a purple fluorescence. Argon is also used in some lasers.
Synonyms and Related Terms
Ar; argo (It.); argônio (Port. Brazil); árgon (Port.); argón (Esp.); Argon (Ces., Dan., Deut., Fr., It., Ned., Pol., Slov., Sven.)
Risks
- Can act as an asphyxiant by displacing air.
- Airgas: SDS
