odine is a chemical element with the symbol I and atomic number 53. It is the heaviest of the stable halogens and exists as a shiny purple-black non-metallic solid under standard conditions that melts to a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius. However, it easily sublimes with gentle heat, resulting in a widespread misconception, even taught in some science textbooks that it does not melt. The element was discovered by the French chemist Bernard Courtois in 1811 and named two years later by Joseph Louis Gay-Lussac, after the Greek ἰώδης “violet”.
Iodine occurs in many oxidation states, including iodide (I−), iodate (IO − 3), and the various periodic anions. It is the least abundant of the stable halogens, the sixty-first most abundant element. It is the heaviest essential mineral nutrient. Iodine is essential in the synthesis of thyroid hormones. Iodine deficiency affects approximately two billion people and is the leading preventable cause of intellectual disability.
The dominant producers of iodine today are Chile and Japan. Iodine and its compounds are mainly used in food. Due to its high atomic number and easy adhesion to organic compounds, it has also been preferred as a non-toxic radiocontrast material. Due to the specificity of the uptake by the human body, radioactive isotopes of iodine can also be used for the treatment of thyroid cancer. Iodine is also used as a catalyst in the industrial production of acetic acid and some polymers.
