WebNov 26, 2024 · Ionization energy, also called ionization potential, is the energy necessary to remove an electron from the neutral atom. X + energy → X+ + e− where X is any atom or molecule capable of being ionized, X + is that atom or molecule with an electron removed (positive ion), and e − is the removed electron. WebIonization energies measure the tendency of a neutral atom to resist the loss of electrons. It takes a considerable amount of energy, for example, to remove an electron from a neutral fluorine atom to form a positively charged ion.

WebEnergy is always required to remove electrons from atoms or ions, so ionization processes are endothermic and IE values are always positive. For larger atoms, the most loosely bound electron is located farther from the nucleus and so is easier to remove. Thus, as size (atomic radius) increases, the ionization energy should decrease.
