WebIonization Energy. Ionization energy (IE) is the amount of energy required to remove an electron from an atom in the gas phase: IE is usually expressed in kJ/mol of atoms. It is always positive because the removal of an electron always requires that energy be put in (i.e., it is endothermic). IE also shows periodic trends. daimler ag careersWebWithin each period, the trend in atomic radius decreases as Z increases; for example, from K to Kr.
