Learning objectives for this unit are to:

Explain how and why Z affects the size and energy of atomic orbitals
Explain the meaning of effective nuclear charge (Z*) in terms of shielding
Rationalize electron configurations in terms of the Pauli Exclusion Principle, the Aufbau principle and Hund’s rule (Pc and Pe)
Write electronic electron configurations for atoms, ions, and excited states
Use Slater’s rules to calculate Z*
Understand how Z* affects the relative energies of atomic orbitals
