Question

Choose the correct ionization potential among the following:

• A.
  $O^{-}>O$
• B.
  $H^{-}>H$
• C.
  $N^{-}>O$
• D.
  None of the above

Answer 1

The correct option is D

None of the above
The size of anion is always greater than the size of the parent atom. Hence, ionization energy decreases in the anion. Therefore, none of the above is the correct answer.
