  Iodine \I"o*dine\ ([imac]"[-o]*d[i^]n or [imac]"[-o]*d[=e]n;
     104), n. [Gr. 'iw`dhs violetlike; 'i`on a violet + e'i^dos
     form: cf. F. iode, iodine. The name was given from the violet
     color of its vapor. See Violet, Idyl.] (Chem.)
     A nonmetallic element, of the halogen group of atomic number
     53, occurring always in combination, as in the iodides. When
     isolated it is in the form of dark gray metallic scales,
     resembling plumbago, soft but brittle, and emitting a
     chlorinelike odor. Symbol I. Atomic weight 126.90. If heated,
     iodine volatilizes in beautiful violet vapors.
     [1913 Webster]
     Note: Iodine was formerly obtained from the ashes of seaweed
           (kelp or varec), but is now also extracted from certain
           natural brines. In the free state, iodine, even in very
           minute quantities, colors starch blue. Iodine and its
           compounds are largely used in medicine (as in
           liniments, antisyphilitics, etc.), in photography, in
           the preparation of aniline dyes, and as an indicator in
           [1913 Webster]
     Iodine green, an artificial green dyestuff, consisting of
        an iodine derivative of rosaniline; -- called also night
     Iodine scarlet, a pigment of an intense scarlet color,
        consisting of mercuric iodide.
     Iodine yellow, a brilliant yellow pigment, consisting of
        plumbic iodide.
        [1913 Webster]

      n 1: a nonmetallic element belonging to the halogens; used
           especially in medicine and photography and in dyes; occurs
           naturally only in combination in small quantities (as in
           sea water or rocks) [syn: iodine, iodin, I, atomic
           number 53]
      2: a tincture consisting of a solution of iodine in ethyl
         alcohol; applied topically to wounds as an antiseptic [syn:

  Dark violet nonmetallic element, belongs to group 17 of the periodic
  table. Insoluble in water. Required as a trace element for living
  organisms. One stable isotope, I-127 exists, in addition to fourteen
  radioactive isotopes. Chemically the least reactive of the halogens, and
  the most electropositive metallic halogen. Discovered in 1812 by
