The electronic configuration which is associated with highest first ionisation enthalpy is:

Options

  1. A[ Ne ] 3 ~s ^2 3 p ^2
  2. B[ Ne ] 3 ~s ^2 3 p ^3
  3. C[ Ne ] 3 ~s ^2 3 p ^4
  4. D[ Ne ] 3 ~s ^2 3 p ^1

Correct answer

B. [ Ne ] 3 ~s ^2 3 p ^3

Step-by-step solution

Half-filled or completely filled orbitals attain extra stability due to symmetrical distribution of electrons and high exchange energy.
