mineralogy elements I Iodine

I - Iodine - NON-METAL HALOGEN

Iodine is a metalloid chemical element belonging to the halogen family and occurring in solid form of an intense violet.

- Iodine is an extremely reactive halogen. It combines with many other chemical elements and forms volatile molecules.
- It also combines with hydrogen to form a liquid compound at low temperatures called hydriodic acid.
- It is very soluble in water and dissolves to form iodide ions.

- Iodine has many uses, including in x-rays, wastewater treatment to remove chlorine and bromides, and the manufacture of chemicals, such as antiseptics, drugs, and dyes.
- It is also used in the treatment of certain forms of cancer and in the production of radiopharmaceuticals for medical diagnostic examinations.
- Iodine is also used in the production of radioactive iodine, which is used in applications such as radio-imaging and cancer treatment.
