Chemistry Question on Electronic Configurations Of Elements And The Periodic Table
Which one of the following statements is incorrect in relation to ionization enthalpy?
Ionization enthalpy increases for each successive electron.
The greatest increase in ionization enthalpy is experienced on removal of electron from core noble gas configuration.
End of valence electrons is marked by a big jump in ionization enthalpy.
Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value.
Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value.
Solution
Electrons in orbitals bearing a lower n value are more attracted to the nucleus than electrons in orbitals bearing a higher nvalue. Hence, the removal of electrons from orbitals bearing a higher n value is easier than the removal of electrons from orbitals having a lower n value.
Therefore, the correct option is (D): Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value.
