You know that the valence electrons are defined as being the electrons located on the highest energy level of that atom, which is given by the principal quantum number, n. Notice that, in iodine's case, the highest energy level is n=5. You have two subshells occupied with electrons on this energy level, 5s2 and 5p5.
