Question

Define ionization enthalpy.

Definition

Solution

The energy required to remove an electron from the isolated gaseous atom in its ground state is called ionization enthalpy (∆iH).
Ionization enthalpy is the quantitative measure of the tendency of an element to lose an electron and expressed in kJ mol-1.
