what is ionization enthalpy

Dear Student

Ionization enthalpy or energy is the energy that is required to remove the most loosely bound electron from the free gaseous atom in its ground state. For example we can analyze ionization energies of Magnesium.

The term ionization energy (EI) of an atom or molecule means the energy needed to remove electrons from an atom. Large atoms require low ionization energy while small atoms require high ionization energy. This quantity was formerly called ionization potential, and was at one stage measured in volts. The name "ionization energy" is now strongly preferred. In atomic physics the ionization energy is measured using the unit "electronvolt" (eV).
