Topics on exam

  • Pauli Exclusion Principle

  • Hund’s Rule

  • Aufbau Principle

  • Diagonal

  • Electron configuration

  • Orbital notation (robbing effect)

  • Electron dot structures

Definitions

  • Heisenberg uncertainty principle - It’s impossible to determine the location of an electron at any given moment because electrons move too fast.

  • Pauli exclusion principle - No more that 2 electrons can be in a box and they must have opposite spins.

  • Hund’s rule - Electrons fill the orbitals of the same energy level one at a time before pairing.

  • Aufbau principle - Lowest energy levels are filled first.
