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.]

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]
