Iodine cycle diagram showing how iodine is cycled through the ecosystem, including living organisms. The figures all have units of teragrams (Tg). Iodine is an essential trace element in biological systems.
Iodine is a chemical element with many uses in medicine, depending on the form. Elemental iodine and iodophors are topical antiseptics. [2] Iodine, in non-elemental form, functions as an essential nutrient in human biology (see iodine in biology).

Iodine is a micronutrient and dietary mineral that is naturally present in the food supply in some regions, especially near sea coasts but is generally quite rare in the Earth's crust since iodine is a so-called heavy element, and abundance of chemical elements typically declines with greater atomic mass.
There are 40 known isotopes of iodine (53 I) from 108 I to 147 I; all undergo radioactive decay except 127 I, which is stable. Iodine is thus a monoisotopic element.. Its longest-lived radioactive isotope, 129 I, has a half-life of 16.14 million years, which is far too short for it to exist as a primordial nuclide.
