ozone
(gcide) | ozone \o"zone\ ([=o]"z[=o]n or [-o]*z[=o]n"), n. [Gr. 'o`zwn
smelling, p. pr. of 'o`zein to smell. See Odor.] (Chem.)
A colorless gaseous substance (O3) obtained (as by the
silent discharge of electricity in oxygen) as an allotropic
form of oxygen, containing three atoms in the molecule. It is
a strong oxidizer, and probably exists in the air, though by
the ordinary tests it is liable to be confused with certain
other substances, as hydrogen dioxide, or certain oxides of
nitrogen. It derives its name from its peculiar odor, which
resembles that of weak chlorine.
