Which one of the following statements is incorrect in relation to ionisation enthalpy?

Options

A. Ionization enthalpy increases for each successive electron.
B. The greatest increase in ionization enthalpy is experienced on removal of electron from core of noble gas configuration.
C. End of valence electrons is marked by a big jump in ionization enthalpy.
D. Removal of electron from orbitals bearing lower `n` value is easier than from orbitals having higher `n` value.

Answer

D

Explanation

Orbitals bearing lower value of n will be more closer to the nucleus and thus electrons will experience greater attraction from nucleus and so its removal will be difficult, not easier.
