Unformatted text preview: Please refer to the “General Study Sheet” Post for information regarding the exams CHAPTER 9 MODELS OF CHEMICAL BONDING INTRODUCTION Our studies in chemistry up to this point have mainly concerned free atoms and ions. Most atoms however, exist in the form of molecules and formula units. It is important to understand why this is the case as well as what the interactions are that hold atoms together in molecules. Three general types of chemical bonding are introduced in this chapter; ionic, covalent, and metallic Covalent bonding is described as the sharing of electrons. It is the mutual attraction of each nucleus for the bonding electrons which provides the driving force for the formation of these compounds. The formation of a covalent bond results in a lowering of the energy for a system. Different covalent bonds have different bond lengths, strengths, and orders. The concept of electronegativity is used to help distinguish between ionic and covalent models of bonding. The differentiation between ionic and covalent is not clear-...
