Question

Which of following is not the correct order?

• A. Electron affinity of $Se>O$
• B. Electron affinity of $B>N$
• C. Electron affinity of $P>N$
• D. None of the above

Answer 1

The correct option is D None of the above

A) Due to its small size, oxygen has the least electron affinity in group 16.

B) Due to the stability of half-filled electronic configuration, nitrogen has a postive electron gain enthalpy and it has lesser electron affinity than B.

C) Due to its small size, the electron affinity of N is smaller than P.

Hence, all of the above are correct.
