- a)The greater increase in ionization enthalpy is experienced on removal of electron from core noble gas configuration
- b)Ionization enthalpy increases on moving from left to right along a period
- c)Ionization enthalpy decreases down the group
- d)Removal of electrons from orbitals bearing lower n value is easier than from orbital having higher n value
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Which of following statement is incorrect regarding ionization enthalp...
The option (d) represents incorrect statement. It states that
"Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value".
The correct statement is "Removal of electron from orbitals bearing lower n value is difficult than from orbital having higher n value".
The attraction between the nucleus and the electron present in orbital having lower n value is higher than the attraction between the nucleus and the electron present in orbital having higher n value.
"Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value".
The correct statement is "Removal of electron from orbitals bearing lower n value is difficult than from orbital having higher n value".
The attraction between the nucleus and the electron present in orbital having lower n value is higher than the attraction between the nucleus and the electron present in orbital having higher n value.

Understanding Ionization Enthalpy
Ionization enthalpy refers to the energy required to remove an electron from an atom or ion. Let's analyze why option 'D' is incorrect.
Core Concepts of Ionization Enthalpy
- Core Noble Gas Configuration: Removing an electron from a core configuration (like that of noble gases) requires significantly more energy because these electrons are closer to the nucleus and are held tightly due to the effective nuclear charge.
- Period Trend: As you move from left to right across a period, ionization enthalpy increases. This is due to the increasing nuclear charge, which pulls the electrons closer to the nucleus.
- Group Trend: Ionization enthalpy decreases down a group because the outer electrons are farther from the nucleus and are shielded by inner electrons, making them easier to remove.
Why Option 'D' is Incorrect
- n Value and Electron Removal: Option 'D' states that removing electrons from orbitals with a lower n value is easier than from those with a higher n value. This is incorrect because electrons in lower energy levels (lower n) are closer to the nucleus and are more tightly bound, requiring more energy to remove.
- Energy Level Comparison: Higher n value orbitals are further from the nucleus and experience more shielding. Therefore, they are generally easier to ionize compared to lower n value orbitals.
Conclusion
In summary, option 'D' is incorrect because it misrepresents the relationship between the principal quantum number (n) and the ease of electron removal. Electrons in lower n orbitals are held more tightly and thus require more energy to be removed, contradicting the statement in option 'D'.
