Before determining which electrons are available for reactions, scientists identify each atom's electron configuration. An informative video from Socratica's chemistry playlist includes how to write electron configurations. It explains the three main rules and works through a few examples to make sure the concept is clear.
- Create practice problems writing electron configuration
- Add each of the following terms to science journals: Aufbau Principle, Hund's Rule, and Pauli Exclusion Principle
- Relies on prior knowledge of electrons and orbitals
- Clear explanation and examples help solidify scholar knowledge
- Requires very little class time
