Polyatomic Ions

For lesson 22, students continued to explore ionic bonds, this time in the context of polyatomic ions.  We worked through the Lesson 22 PowerPoint and then students used the class period to practice creating and naming polyatomic ions and their chemical formulas using the Lesson 22 worksheet.  For homework, students should complete questions 1-6 on page 111 and read Lesson 23 in advance of Monday’s lesson.
