Explanation:
Detailed explanation-1: -Iodine has 7 valence electrons in the valence shell which means that there are 7 electrons in its outer shell. A neutral iodine atom will have a total of 53 electrons around its nucleus.
Detailed explanation-2: -Valence electrons are the number of electrons present in the outermost shell of an atom. Now, the last shell of chlorine atom has 7 electrons in it. Therefore, there are 7 valence electrons present in an chlorine atom.
Detailed explanation-3: -Iodine has an electron configuration of [Kr]4d105s25p5, with the seven electrons in the fifth and outermost shell being its valence electrons.
