Iodine
(gcide) | 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
titration.

iodine
(wn) | iodine
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:
tincture of iodine, iodine] |
iodine
(elements) | iodine
Symbol: I
Atomic number: 53
Atomic weight: 126.904
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
Courtois.
