Students began class by looking at a PopaPodcast on writing Ionic Formulas with Polyatomic Ions. Upon conclusion of the podcast, we worked 4 problems involving polyatomic ions on the board as a class. Then, we began work on the "Writing Ionic Formulas with Polyatomic Ions".(50 pts). We will be working on the Chemical Naming and writing formulas for ionic & covalent compounds this week.
