Orbitals Shapes

- How do Quantum Numbers relate to orbitals?
- iPad app = Atom in a Box (electron probability density) [LINK]
- different orbital shapes (s, p, d, f)
- The Orbitron! [FUN]

Orbital FIlling

- not all orbitals on a level are the exact same energy

Electron Configurations

- atoms with more than one electron fill in this order (shown above)
- use shorthand notation (examples)
- In orbital sub levels – filling order very specific (example)
