In which types of orbitals, such as p, d, or f, does the pairing of electrons occur later, following Hund's rule?

Options

  1. AP orbitals with the entry of the 2nd electron.
  2. BD orbitals with the entry of the 3rd electron.
  3. CF orbitals with the entry of the 7th electron.
  4. DP orbitals with the entry of the 4th electron.

Correct answer

C. F orbitals with the entry of the 7th electron.

Step-by-step solution

"pairing of electrons will start in the p, d and f orbitals with the entry of 4th, 6th and 8th electron, respectively."
