Question

The correct order of ionisation energy for comparing carbon, nitrogen and oxygen atoms is

  1. (a) C greater than N greater than O  
  2. C greater than N less than O  
  3. (c) C less than N greater than O  
  4. C less than N less than O  

The correct answer is: (c) C less than N greater than O


    Nitrogen has more ionisation potential than carbon & oxygen because, if outermost orbit is half filled so it is more stable & order is C less than N greater than O
