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¡ C. and to a solid melting at -189.6¡ 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¡ C. and 760 mm., 1.7828 g.

A gaseous element, symbol A, atomic weight 39.6, present in the atmosphere in the proportion of about 1 per cent. It is chemically very inert, but a compound with carbon has been obtained, and it is believed to unite with magnesium at a very high temperature.
