In physics and chemistry, ionization energy (IE) (American English spelling), ionisation energy (British English spelling) is the minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule. The first ionization energy is quantitatively expressed as X(g) + energy ⟶ X (g) + e Webb-Ionization energies are all endothermic. -First ionization energies are exothermic, while second and successive ionization energies are endothermic. -Ionization energies are all exothermic. -Ionization energies for removing valence electrons are exothermic and endothermic for removing core electrons. Ionization energies are all endothermic
