Iodine is a chemical element with symbol I and atomic number 53. The name is from Greek á¼°Î¿ÎµÎ¹Î´Î®Ï ioeidÄs, meaning violet or purple, due to the color of elemental iodine vapor. Iodine and its compounds are primarily used in nutrition, and industrially in the production of acetic acid and certain polymers. Iodine's relatively high atomic number, low toxicity, and ease of attachment to organic compounds have made it a part of many X-ray contrast materials in modern medicine.
Iodine is a trace mineral required by the body for the synthesis of the thyroid hormones, T4 and T3. T4 contains 4 iodine atoms and when one of the iodine atoms is stripped off of T4, it becomes T3, with 3 iodine atoms remaining.luoride has the potential to impair thyroid function and was used as a thyroid-suppressing medication for patients with hyperthyroidism. Fluoride was utilized because it was found to be effective at reducing the activity of the thyroid gland â even at doses as low as 2 mg/day.
