Apr 19, 2017 · Iodine is the 61st element in terms of abundance, making it not only one of the least abundant nonmetallic elements on Earth but also one of the rarest elements needed for life. Although...
Iodine - Element, Halogen, Gas: Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states.
Interesting Facts. Iodine Cost. What is Iodine. A crystalline metalloid, iodine (pronounced EYE-eh-dine) belongs to the family of halogens. Denoted by the chemical symbol I, it undergoes sublimation when heated to form a purple gaseous vapor, sometimes called as Iodine gas whose molecular formula is I 2.
Iodine's chemical properties are similar to the lighter halogens above it, fluorine, chlorine, and bromine. But its physical appearance is very different. It is a steel-gray solid that changes into beautiful purple vapors when heated. Iodine was discovered in 1811 by French chemist Bernard Courtois (1777-1838).
