Quantum Numbers, Atomic Orbitals, and Electron Configurations

Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD you will know what they are. But let Professor Dave give you a head start!
