Unit Objectives
- Derive the predicted ground-state electron configurations of atoms
- Identify and explain exceptions to predicted electron configurations for atoms and ions
- Relate electron configurations to element classifications in the periodic table
- Describe and explain the observed trends in atomic size of the elements
- Describe and explain the observed trends in ionization energy of the elements
- Describe and explain the observed trends in electron affinity and metallic character of the elements
- To recognize the inverse relationship of ionization energies and electron affinities
