AP Chemistry 14-­‐15 Unit 3: Chemical Bonding Chapters 7,8 and 9 Note: The teacher will cover the majority of the topics outlined below, but not all of them. Students are responsible for all of these topics. Also note that particulate diagrams are now considered very important by the CB (see the notes).` Chapter 7 (3 days) Lewis dot formulas for atoms and valence electrons (pg 267) Access notes 3-­‐1 by:_______________ Types of bonds and properties (pg 267) Valence electrons and atomic lewis structures (pg 267-­‐268) Formation of ionic compounds (pg 268-­‐275) Note that the Born Haber cycle on page 274 is not important, but you should understand the individual pieces, such as ionization energy and electron affinity.
