i·o·dine

 (ī′ə-dīn′, -dĭn, -dēn′)
n.
1. Symbol I A lustrous, purple-black, corrosive, poisonous halogen occurring as a diatomic molecule, I2, that easily sublimes to give a purple gas and is a trace element essential for proper thyroid function. Radioactive isotopes, especially I-131, are used as medical tracers and in thyroid disease diagnosis and therapy. Iodine compounds are used as germicides, antiseptics, and dyes. Atomic number 53; atomic weight 126.9045; melting point 113.7°C; boiling point 184.4°C; density of gas 11.27 grams per liter; specific gravity (solid, at 20°C) 4.93; valence 1, 3, 5, 7. See Periodic Table.
2. An antiseptic preparation containing iodine in solution, used to treat wounds.

[French iode, iodine (from Greek ioeidēs, violet-colored : ion, violet; akin to Latin viola; see viola2 + -oeidēs, -oid) + -ine.]

iodine

(ˈaɪəˌdiːn)
n
(Elements & Compounds) a bluish-black element of the halogen group that sublimates into a violet irritating gas. Its compounds are used in medicine and photography and in dyes. The radioisotope iodine-131 (radioiodine), with a half-life of 8 days, is used in the diagnosis and treatment of thyroid disease. Symbol: I; atomic no: 53; atomic wt: 126.90447; valency: 1, 3, 5, or 7; relative density: 4.93; melting pt: 113.5°C; boiling pt: 184.35°C
[C19: from French iode, from Greek iōdēs rust-coloured, but taken to mean violet-coloured, through a mistaken derivation from ion violet]

i•o•dine

(ˈaɪ əˌdaɪn, -dɪn; in Chem. also -ˌdin)

also i•o•din

(-dɪn)

n.
a nonmetallic halogen element occurring as a grayish-black crystalline solid that sublimes to a dense violet vapor when heated: used as an antiseptic, as a nutritional supplement, and in radiolabeling. Compare radioiodine. Symbol: I; at. wt.: 126.904; at. no.: 53; sp. gr.: (solid) 4.93 at 20°C.
[1814; < French iode < Greek īṓdēs violet-colored, derivative of íon violet]

i·o·dine

(ī′ə-dīn′)
Symbol I A shiny, grayish-black halogen element that is corrosive and poisonous. It occurs in very small amounts in nature but is abundant in seaweed. Iodine compounds are used in medicine, antiseptics, and dyes. Atomic number 53. See Periodic Table.
