  1. Where is the Electron Located?

  2. The Quantum Model of the Atom • Heisenberg uncertainty principle: It is impossible to determine both the position and velocity of an electron or any other particle

  3. What is the Address of the Electron? • Principle Quantum Number (n): Indicates the energy level occupied by an electron. • Angular Momentum (l): Indicates the shape of the orbital (s,p,d,f,g)

  4. Atomic Numbers and Quantum Numbers • Magnetic Quantum Number (m): Indicates the orientation of an orbital around the nucleus. • Spin Quantum Number (↓↑): Indicates which way the electron is spinning

  5. What are the Rules Governing Electron Configuration? • Aufbau Principle: An electron occupies the lowest energy orbital available • Pauli Exclusion Principle: Only two electrons per orbital and they must spin in opposite directions • Hund’s Rule: Each orbital of equal energy must have one electron before a second electron is added

  6. Let’s Fill Up The Orbitals!

  7. Summary of Orbitals

  8. Predicting the 1s Orbital

  9. Exceptions to Aufbau
