Ar"gon (&?;), n. [Gr. &?; inactive.]
(Chem.) A substance regarded as an element, contained in the
atmosphere and remarkable for its chemical inertness. Rayleigh
and Ramsay.
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° 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.
