Using Hund’s Rule

Process information from secondary sources to use Hund’s rule to predict the electron configuration of an element according to its position in the Periodic Table

  • Hund’s rule states that the distribution of electrons in a free atom occur so that as many orbitals as possible are occupied by a single electron (spinning identically) before pairing of electrons with opposite spins occurs
    • Three p orbitals
    • Five d orbitals
    • Seven f orbitlas
  • Prediction examples: Seventh nitrogen

  • Prediction examples: Eighth Oxygen

  • Therefore has opposite spin
