Solution

The deviation in the ionization enthalpy of some elements from the general trend can be explained by the points as given below:-

(i) The fully filled and half-filled orbital provide extra stability due to the symmetry.

(ii) The effective nuclear charge.

(iii) The \[\ce{e- - e-}\] repulsion which lead to instability.
