Study Notes
Atomic Orbitals
- The shape of an s-orbital is spherical and symmetrical around the nucleus.
- The shape of a p-orbital is dumbbell-shaped and oriented in a specific direction.
Electron Accommodation
- According to Pauli's Exclusion Principle, an orbital can accommodate a maximum of two electrons.
Aufbau Principle
- The Aufbau Principle states that electrons occupy the lowest available energy states (orbitals) in an atom.
Hund's Rule
- Hund's Rule applies in degenerate orbitals, where electrons occupy orbitals of equal energy in a way that maximizes the total spin.
- It applies when filling degenerate orbitals, where the energy difference between orbitals is zero or very small.
