1.3: Multi-Electron Atoms
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
