Among the second-period elements, the actual ionisation enthalpies are in the order Li i H than N and F?

Options

  1. Abecause Oxygen has more protons in its nucleus than N and F.
  2. Bbecause Oxygen has a larger atomic size compared to N and F.
  3. Cbecause Oxygen has a half-filled p-subshell, which makes it easier to remove an electron
  4. Dbecause Nitrogen has a half-filled stable electronic configuration and Fluorine has a higher Z eff as well as

Correct answer

D. because Nitrogen has a half-filled stable electronic configuration and Fluorine has a higher Z eff as well as

Step-by-step solution

Correct Option is : (D) because Nitrogen has a half-filled stable electronic configuration and Fluorine has a higher Z eff as well as smaller size
