Iodine is a chemical element. The body needs iodine but cannot make it. The needed iodine must come from the diet. As a rule, there is very little iodine in food, unless it has been added during processing, which is now the case with salt. Most of the worldâs iodine is found in the ocean, where it is concentrated by sea life, especially seaweed.
Iodine has only one stable isotope. A number of iodine radioisotopes, such as 131 I, are also used in medical applications. Iodine is found on Earth mainly as the highly water-soluble iodide ion Iâ , which concentrates it in oceans and brine pools. Like the other halogens, free iodine occurs mainly as a diatomic molecule I 2, and then only momentarily after being oxidized from iodide by an oxidant like free oxygen.
