Assertion: (A) Generally, ionsiation enthalpy increases from left to right in a period. Reason ( R) When successive electrons are added to the orbitals in the same principle quantum level, the shielding effect of inner core of electrons does not increase very much to compensate for the increased attraction of the electrons to the nucleus.
