Which of the following statements correctly describe ionization energy? [Select all that apply.] IE1 for a given element is always larger than IE2. lonization energy is always postive (i.e., endothermic) lonation energy is always negative (i.e., exothermic) The ionization energy increases for the removal of each subsequent electron The ionization energy describes the energy needed to add an electron to a neutral atom. IE, for a given element is never larger than IE2. IE, for a given element is sometimes larger than IE2.
