Questions and Answers

According to the Pauli Exclusion Principle, why do no two electrons share the same combination of 4 quantum numbers?

  • Electrons occupy different orbitals
  • Electrons repel each other
  • Electrons have different energy levels
  • Electrons have opposite spins (correct)

    • Which rule states that in orbitals of equal energy, the lowest energy configuration is that with the maximum number of unpaired electrons?

  • Penetration Rule
  • Hund's Rule (correct)
  • Aufbau Principle
