This is the sixth chapter in an 18 chapter interactive text for introductory chemistry at the college or Honors/AP high school level. The book contains video demonstrations, animations, photo galleries, checkpoints, audio introductions to each chapter, as well as methodology, visualization, and sample problems all done by sequential, progressive disclosure of the answer. The book has a continuing emphasis on ways to learn chemistry, with hints, additional help in scrolling sidebars or “pop-ups,” as well as video clips of student preceptors’ views on how they successfully mastered chemistry. The organization of the text allows the student to learn the basic concepts related to the bonding and structure of matter in the first eight chapters and then tackle the concepts necessary for an understanding of the reactions of matter—stoichiometry, thermodynamics and kinetics, and the four types of reactions with an emphasis on acids and bases. The text integrates organic and inorganic examples and nomenclature.
This chapter provides an introduction to the Lewis model (electron-dot), the valence bond model, and the molecular orbital model. These models provide a way to rationalize the binding between the atoms in covalent compounds. This chapter is essential for understanding the structure and bonding of compounds.
