Iodine

Iodine (pronounced /ˈaɪədaɪn/, /ˈaɪədɨn/, or in chemistry /ˈaɪədiːn/; from Greek: ιώδης iodes "violet"), is a chemical element that has the symbol I and atomic number 53. Naturally-occurring iodine is a single isotope with 74 neutrons. Chemically, iodine is the second least reactive of the halogens, and the second most electropositive halogen; trailing behind astatine in...
