Background; Iodine and its compounds are primarily used in medicine, photography, and dyes. Iodine is rare in the solar system and Earth's crust. The iodides are very soluble in water, and the element is concentrated in seawater. This mechanism helps to explain how the element came to be required in trace amounts by all animals and some plants, being the heaviest element commonly used by living organisms (only tungsten, used in enzymes by a few bacteria).
