Chapter Objectives
Chapter 9 & 2 - Chemical Bonding, Ionic Bonding, Naming Ionic Compounds
Sections 9.1, 2.7, 9.2 2.8 (pp. 64-70)
9.1 - Atomic Properties and Chemical Bonds
Concepts
- Be able to describe how difference in atomic properties lead to differences in bond type. Be able to distinguish between the three types of bonding.
- Assigned problems: 9.1, 9.3
Skills
- Assigned problems: 9.4, 9.6, 9.8, 9.10, 9.12, 9.14
2.7 - Compounds: Introduction to Bonding
Concepts
- Be able to describe the essential features of ionic and covalent bonding and the distinction between them.
- Assigned problems: 2.60, 2.61, 2.62, 2.63, 2.64, 2.66, 2.69
Skills
- Be able to predict the monatomic ion formed from a main-group element.
- Sample problem 2.6
- Assigned problems: 2.70, 2.71, 2.72, 2.74, 2.76
9.2 - The Ionic Bonding Model
Concepts
- Be able to describe the essential feature of ionic bonding: electron transfer to form ions, and their electrostatic attraction to form a solid.
- Be able to discuss how the lattice energy is ultimately responsible for formation of ionic compounds.
- Be able to describe how ionic compound formation is conceptualized as occurring in the hypothetical steps (Born-Haber cycle) to calculate lattice energy.
- Be able to describe how Coulomb’s law explains the periodic trends in lattice energy.
- Be able to describe why ionic compounds are brittle and high melting and conduct electricity only when molten or dissolved in water.
