Argon is considered a rare atmospheric gas which is colorless, odorless, tasteless and nontoxic. It is considered extremely inert and forms no known chemical compounds.

Argon is slightly soluble in water. The concentration of Argon in the atmosphere by volume is 0.93%. Argon is principally shipped and used in gaseous form for neon signs, lasers,incandescent and fluorescent lamps, electronic tubes, window insulation, welding, and semiconductor applications.
