Overview: This is a review unit. Much of the material, except for periodic relationships, was covered in
Chemistry I/IH. Please complete the materials in this study guide in preparation for a class discussion upon
return from break. We will then learn about periodic relationships, and the mathematical applications and test
out on the material. If you need help, there will be study sessions on Thursday, 11/19/15 AND Monday,
11/30/15 during lunch and after school.
TO DO:
1. Read Chapters 6, 7 and 21 and take notes. If a section is REVIEW: Make sure to summarize all the key ideas,
and make note of all key formulas and equations (unless otherwise noted.) If a section is NEW: Take thorough
notes, unless otherwise indicated.
2. Complete the questions and/or assigned problems for each section.
3. Come to study session on Thursday, 11/19/15 or Monday, 11/30/15 for help completing the study guide.
