The periodic table shows which elements are in each group. It has low conductivity, a dull appearance, and tends to gain electrons in reactions, which are typical characteristics of nonmetals. Iodine, with an atomic number of 53, is located in Group 17 (the halogens) and Period 5. Its behavior in forming the iodide anion is a classic nonmetal reaction, contrasting with the tendency of metals to lose electrons. Iodine is a chemical element; it has symbol I and atomic number 53.
