Chemicals - Iodine

Iodine is a chemical element with the element symbol I (before the international element symbol introduction it was J) and the atomic number 53. In the periodic table it is in the 7th main group or the 17th IUPAC group and thus belongs to the halogens. The name is derived from the ancient Greek word “ioeides” (ιο-ειδής) meaning “violet-colored, violet”. Vapors produced during heating are characteristically violet. Older names include iodium, iodina, and iodine. Iodine is a solid at room temperature, poorly soluble in water, but readily soluble in aqueous potassium iodide solution (see Lugol’s solution) and very soluble in ethanol and other organic solvents.
