Which one of the following statements is incorrect in relation to ionisationenthalpy ?
A
Ionization enthalpy increases for each successive electron.
B
The greatest increase in ionization enthalpy is experienced on removal of electron from core of noble gas configuration.
C
End of valence electrons is marked by a big jump in ionization enthalpy.
D
Removal of electron from orbitals bearing lower n value is easier than from orbitals having higher n value.
Answer
Removal of electron from orbitals bearing lower n value is easier than from orbitals having higher n value.
Explanation
Solution
Orbitals bearing lower value of n will be more closer to the nucleus and thus electrons will experience greater attraction from nucleus and so its removal will be difficult, not easier.
