Which of the following statements is incorrect in relation to ionization enthalpy?
Correct answer: D. Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value.
- 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 orbital having higher n value.
Explanation
Removal of Electron from orbital bearing lower n value is difficult than from orbitals having higher n values. Option D is correct.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
