Iodine is found on Earth mainly as the highly water-soluble iodide ion I − , 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. In the universe and on Earth, iodine's high atomic number makes it a relatively rare element . Its presence in ocean water has given it a role in biology. It is the heaviest essential element used widely by life i
