The correct answer is:<br /><br />C. It indicates which energy level the valence electrons are located in for the element.<br /><br />Explanation:<br /><br />The valence electrons of an element are the electrons in the outermost energy level (shell) of the atom. The group number on the periodic table indicates the number of valence electrons for the element.<br /><br />A. It indicates how many valence electrons the element has.<br />This is correct. The group number corresponds to the number of valence electrons for the element.<br /><br />B. It indicates how many valence electrons the element will lose to form an ion.<br />This is not correct. The group number does not indicate how many valence electrons the element will lose to form an ion.<br /><br />C. It indicates which energy level the valence electrons are located in for the element.<br />This is correct. The group number indicates the energy level (shell) where the valence electrons are located.<br /><br />D. It indicates how many valence electrons the element will gain to form an ion.<br />This is not correct. The group number does not indicate how many valence electrons the element will gain to form an ion.<br /><br />Therefore, the correct answer is C. It indicates which energy level the valence electrons are located in for the element.
