उत्तर
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.

Explain the following:
Ionisation enthalpy decrease in a group from top to bottom?
Assertion (A): Generally, ionisation enthalpy increases from left to right in a period.
Reason (R): When successive electrons are added to the orbitals in the same principal quantum level, the shielding effect of inner core of electrons does not increase very much to compensate for the increased attraction of the electron to the nucleus.
