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

Content

• How are Macroscopic Properties related to Bonding?
• Atomic Structure and Periodic Table
• Major Results from Quantum Mechanics
• Primary Bonding
• Macroscopic Properties:
  • Force vs Extension
  • Stress-Strain Curves
  • Types of Bonding between Atoms Inferred from Bonding
  • Elastic Moduli
  • Coefficient of Thermal Expansion
• Summary: Bonding, Structure, Properties
• Energy vs Volume : Bulk Modulus
• Example Test Question
