Iodine (from the Greek word Iodes, meaning "violet"), is a chemical element in the periodic table that has the symbol I and atomic number 53. It is required as a trace element for most living organisms. Chemically, iodine is the least reactive of the halogens, and the most electropositive halogen. It should be noted that astatine is expected to be even less reactive and more electropositive, but the rarity of astatine makes it difficult to confirm this. Iodine is primarily used in medicine, photography and in dyes.
As with all other halogens (members of Group VII in the Periodic Table), iodine forms diatomic molecules, and hence, has the molecular formula of I2.
= Occurrence on earth = Iodine occurs in the environment chiefly as disolved iodide in seawater. However, it is present in some minerals and soils as well. The element may be prepared in an ultrapure form through the reaction of potassium iodide with copper (II) sulfate. There are also several other methods of isolating this element. Although the element is actually quite rare, kelp and certain other plants have the ability to concentrate iodine, which helps introduce the element into the food chain as well as keeping its cost down.
