Iodine is a non-metallic, dark-gray/purple-black, lustrous, solid element. Iodine is the most electropositive halogen and the least reactive of the halogens even if it can still form compounds with many elements. Iodine sublime easily on heating to give a purple vapour. Iodine dissolves in ...
305: "La substance nouvelle, que depuis on a nommé iodeà cause de la belle couleur violette de sa vapeur, a bien tout l'aspect d'un métal." ("The new substance, which since has been named iode because of the beautiful violet color of its vapor, has all the appearance of a metal...
(developed to overcome a British naval blockade) used ashes of iodine-rich seaweed as one of its ingredients. It was while cleaning out waste deposits with acid and heat that Courtois noticed beautiful violet-colored vapors that deposited as metal-like black crystals on the cooler surfaces of ...

It is also used in the production of vanadium metal in the McKechnie-Seybolt process, which is the reduction of vanadium pentoxide in the presence of iodine. Iodine is used in a similar manner in the production of high-purity zirconium. For many years, iodine tincture(3% to 7% dissolved ...
Lower iodides may be produced either through thermal decomposition or disproportionation, or by reducing the higher iodide with hydrogen or a metal, for example:[55] Most metal iodides with the metal in low oxidation states (+1 to +3) are ionic. Nonmetals tend to form covalent molecular iodid...
the production of certain transition metals in a high state of purity, among themtitanium,zirconium,thorium,chromium, andcobalt.

Although it is technically a non-metal, it exhibits some metallic qualities. Iodine is classified as a halogen — a subset of very chemically reactive elements (Group 17 on the periodic table) that exist in the environment as compounds rather than as pure elements. The other halogens include...
Iodine is a non-metal substance with a wide variety of industrial and pharmaceutical uses. It is also a vital nutrient. People with iodine deficiencies often develop neck bulges around their thyroid called goiters.Answer and Explanation:
In addition to noble metals, iodine is combined with all the metal to produce iodide; combined with non-metal to produce covalent iodide; combined with other halogens to produce interhalogen compounds, such as iodide iodide, iodine iodide, iodine and so on. Iodide ion is a strong reducing ...
