The ionization energy (Ei) is qualitatively defined as the amount ofenergy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation. It is quantitatively expressed in symbols as X + energy → X+ + e−

Heya. !!!!

The energy required to remove a valence electron from an isolated atom in its gaseous state is called ionization energy or ionization enthalpy. It unit is kJ/mol. Ionization enthalpy is always positive.
●the size of an atom, lower is its ionization energy and vice versa.
●the effective nuclear charge, higher is ionization enthalpy and vice versa.
●Presence of d and/or f orbital increases ionization enthalpy.
●Fully filled and half field orbitals are extra stable, so removal of electron from these orbitals is not easy. Hence, ionization enthaly is more in these cases.
Hope you got the answer!
