The first ionisation potentials of four consecutive elements, present in the second period of the periodic table are 8.3, 11.3, 14.5 and 13.6 eV respectively. Which one of the following is the first ionisation potential (in eV) of nitrogen?
  • a)
    13.6
  • b)
    11.3
  • c)
    8.3
  • d)
    14.5
Correct answer is option 'D'. Can you explain this answer?

Yes , the correct answer is D=14.5 Because Nitrogen has higher Ionic Potential(IP) than Oxygen (on its right) and carbon(on its left) Now question arise why nitrogen has higher potential than oxygen even when IP increases left to righ in periodic table ? And the answer for this question is : nitrogen has half filled 2p subshell which a stable configuration and it don't wa... more
