Unformatted text preview: Chapter 10 Part 1 Page 1 of 3 Chapter 10: Molecular Geometry and Chemical Bonding Theory Part 1 In the first part of this chapter we use the Lewis ElectronDot formula to determine the arrangement of the electron pairs (or really, the regions of electron density) the molecular geometry The basis of both of these is that regions of electron density repel each other and so will be arranged as far apart as possible. As a result, we can predict the arrangement of these regions of electron density. Note: The text uses electron pairs to mean regions of electron density. The distinction is needed when dealing with a formula that has a multiple bond. All of the electrons in that bond are considered to be one region of electron density.
