Refortify your chemistry - Atomic scale structures
Goals
- Define basic concepts:
- Filling of Atomic Energy Levels: Pauli Exclusion Principle
- Atomic Orbitals (s-, p-, d-, and f- type electrons)
- Types of Bonding between Atoms
- The Periodic Table (and solid state structures)
- Bond Energy Curves
- Describe how types of bonding affect Bond-Energy Curves
- Describe how the Bond-Energy Curve describes macroscale properties
Learning Objective
- Know, and be able to use, filling of atomic levels to get ionic electron configurations of atoms
- Use the Bond-Energy Curve to describe qualitatively the difference types of materials and their macroscale properties
- Know the origins of stress and strain, melting temperature, and thermal expansion
