Question
Name the factors on which ionization enthalpy depends?
Solution
Ionization enthalpy depends on the following factors:
- Atomic Size: Larger atoms have lower ionization enthalpy.
- Nuclear Charge: Higher nuclear charge increases ionization enthalpy.
- Shielding Effect: More shielding lowers ionization enthalpy.
- Electron Configuration: Stable configurations (noble gases, half-filled, fully filled) have higher ionization enthalpy.
- Effective Nuclear Charge (Zeff): Higher Zeff increases ionization enthalpy.
- Nature of the Electron to be Removed: Electrons from stable orbitals require more energy to remove.
