Chapter 9- Molecular Geometry and Bonding Theories 9.1 Molecular Shapes Lewis structures give atomic connectivity: they tell us which atoms are physically connected to which atoms. Whenever two atoms or ions are strongly attached to each other we say there is a chemical bond. Three general types of chemical bonds: ionic , covalent and metallic. We will encounter 11 basic molecular shapes: The shape of a molecule is determined by its bond angles. Bond angles The angles made by the lines joining the nuclei of the atoms in a molecule Consider CCl4: Experimentally we find all Cl?C?Cl bond angles are 109.5?. Valence Shell Electron Pair Repulsion (VSEPR) model.
