Our Unit 3 Test will be on how we find out how much of a substance we have: using moles, or percent composition. It will also include questions on ionic bonding and naming and writing formulas for ionic compounds. Here is the blank study guide. I recommend that you complete the study guide and make sure you know how to do the problems for each learning target. I will post the answers on Sunday, Dec. 4.

Classwork Sept. 30/ Oct. 3
Sept. 28/29 : Naming Ionic Compounds and Reviewing Vocabulary
If you were absent from class today, or just need a review, today our guiding question was:
How do we know what to name compounds, and we do we give them a name that is different from the elements that make them up? For example, “Why is AlCl3 called aluminum chloride?”
Here is a picture of the Table of Contents from today:
By the end of the lesson today, you will have learned how to:
- Write the symbol and charge of an ion after being given the number of protons and electrons;
- Write the formula of an ionic compound after being given the ions or the name;
- Write the name of an ionic compound after being given the formula;
- Define an ionic bond and explain how it holds ions together in a molecule.
