Iodine is the least reactive member of the halogens, which include fluoride, chlorine, and bromine. Iodine is a gray to purplish-black crystalline element that rarely occurs in nature in the elemental state, but is produced from naturally occcuring iodine compounds. It melts at 113°С,boils at 185°С, and sublimes readily. Iodine forms compounds with all the elemenets except sulfur, selenium, and the inert gases; dissolves in water, salt solutions and certain organic solvents.
