For an element having only valence shell electron, then which of the following ionisation energy difference will have the maximum value-

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.
