Iodine is the element with the symbol I and atomic number It is a reactive halogen which is volatile and has many uses in inorganic and organic chemistry. Unlike the other halogens, iodine is solid at standard conditions and does not sublime rapidly, thus can be handled much safer. Iodine can be seen in the form of royal dark purple crystals, or in a gas in a lighter color. It is most commonly found as a silvery metallic looking chemical. Iodine, like other halogens, has its own unique smell, somewhat similar to chlorine , or described as being "clean".
