Webionization energy (IE) the energy required to remove an electron from a gaseous atom in its ground state first and second ionization energy the energy required to remove the most loosely bound electron from a gaseous atom in its ground state are ionization processes exothermic or endothermic? always exothermic and IE is always positive WebIonization energy is the amount of energy required to remove the outer shell electron of an atom. It's directly proportional to the effective nuclear charge of an atom. As the size of an atom increases the Z eff also increases means IE increase. Among given atoms Na,Mg,Al and Si the atomic size of Si is maximum therefore it has highest IE and ...
