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.
