Learning Outcomes

  • Aufbau Principle: Electrons fill lower energy levels first (1s → 2s → 2p).
  • Pauli Exclusion: No two electrons can have the same 4 quantum numbers. (Pairs must have opposite spin ↑↓).
  • Hund's Rule: For degenerate orbitals (like p), fill singly first (↑ ↑ ↑) before pairing.
  • Try: Drag the 3D canvas. Click an electron to see its quantum numbers.
