Ionic Compounds

We extended our learning about ions to the study of ionic compounds, reviewing Lesson 17-19 content in preparation for the mini-quiz tomorrow.  We then worked through the Lesson 20 PowerPoint which included the vocabulary terms of cation and anion and learning about how different numbers of anions and cations combine by following the Rule of Zero Charge.  Students received a handout containing common ions and their charges to use as a resource, and we worked through the first few problems on the back of the Lesson 20 Worksheet.  Students should continue working on the Lesson 20 worksheet after the mini-quiz tomorrow and this weekend as time permits.  We will review a selection of the problems from the worksheet on Monday.
