List the properties of ionic crystals, and relate them to the lattice energy.Sketch the potential energy as a function of inter-ionic separation.Understand the valence shell electron pair repulsion (VSEPR) model.Describe quantitatively the energetic factors and characteristics involved in the formation of an ionic bond.Learning ObjectivesĪfter completing this session, you should be able to:
Sadoway discusses the shortcomings of ionic bonding and Lewis's concept of shell filling by electron sharing including the Lewis dot notation ( Session 9) and returns to the valence shell electron pair repulsion (VSEPR) model in Session 11: The Shapes of Molecules.
