The minimum amount of energy required to remove the most loosely bound electron from an isolated atom in the gaseous state in known as ionisation energy or ionisation enthalpy (IE_1) of the element. The energy required to remove the second electron from the monovalent cation is called second ionisation enthalpy (IE_2) . Similarly, we have third, fourth ..... inonisation enthalpies. The values of ionisation energy depends on a number of factors such as (i) size of the atom (ii) screening effect (iii) nuclear charge (iv) half filled and fully filled orbitals (v) shape of orbital. In a group, the ionisation energy decreases from top to bottom. In a period, the value of ionisation energy increases from left to right. In a period, the ionisation energy is lowest for the :
