Mineral Species sorted by the element I Iodine

Iodine (I ) by %

**Iodine (I) Element Properties**
Atomic Mass	126.90447
Atomic Number	53
Name Origins	Greek, iodes = "violet."
Year Discovered	1811
Discovery Credits	Discovered by B. Courtois at Paris, France.
Remarks	Black, shiny non-metal solid, I2. Sublimes easily. Used in disinfection, pharmaceuticals, food supplements, dyes, catalysts and photography. Diagnostic tests: Iodine salts (along with F, Cl, and Br) will give a blue color to flames when heated on a copper disk. Treatment of the salt with concentrated H₂SO₄ acid will effervesce with the evolution of a violet, sharp smelling gas (l₂). Iodine is sometimes found associated with chlorine or bromine so a precipitate with AgNO3 solution is white (AgCl), cream (AgBr), or yellow (AgI) depending on which anion predominates. The precipitate is soluble in NH₄OH.
