Iodine is a purple-black solid that sublimes at standard temperatures into purple-pink gas with an irritating odor. This element is essential in daily human consumption and is necessary in the production of the thyroid hormone. Table salt is often enriched with iodine to ensure daily levels are met, hence the name iodized salt. Lack of this element in babies and small children can cause mental retardation, and in adults, mental slowing. Iodine is an important material in several applications, including pharmaceuticals, antiseptics, and medicine.
