Question

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

• 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 1

Answer: (D)

As the value of $n$ increases the atomic size increases and ionsadon enthalpy decreases
