FAQs: Metallic Iodine

Metallic iodine, also known as molecular iodine (I₂), is a chemical element with the symbol I and atomic number 53. It appears as a lustrous, dark gray or purple-black solid at room temperature and sublimes easily to form a violet vapor.

Yes, metallic iodine is a chemical element classified as a halogen in Group 17 of the periodic table. It is a non-metal and is the least reactive of the halogens, though it readily forms compounds with many elements.

Properties of metallic iodine include a melting point of 113.7°C and a boiling point of 184.4°C. It has a density of 4.933 g/cm³ and sublimes to form a violet gas. Iodine is moderately reactive and is used in various applications, including medicine and photography.

The molecular formula of metallic iodine is I₂, indicating that it consists of two iodine atoms bonded together. This diatomic molecule is the elemental form of iodine found in nature.

Metallic iodine is used in various applications such as in the production of iodized salt, as a disinfectant, and in the synthesis of iodine compounds. It also plays a role in medical imaging and as a catalyst in certain chemical reactions.
