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

Options

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

Answer

D

Explanation

As the value of n increases the atomic size increases and ionsation enthalpy decreases.
