  Argon \Ar"gon\, n. [NL., fr. Gr. ?, neut. of ? inactive; ? priv.
     + ? work.] (Chem.)
     A colorless, odorless gas occurring in the air (of which it
     constitutes 0.93 per cent by volume), in volcanic gases,
     etc.; -- so named on account of its inertness by Rayleigh and
     Ramsay, who prepared and examined it in 1894-95. Symbol, A;
     at. wt., 39.9. Argon is condensible to a colorless liquid
     boiling at -186.1[deg] C. and to a solid melting at
     -189.6[deg] C. It has a characteristic spectrum. No compounds
     of it are known, but there is physical evidence that its
     molecule is monatomic. Weight of one liter at 0[deg] C. and
     760 mm., 1.7828 g.
