· Memorize the names and formulas of the common polyatomic ions, on page 65 of the book (Table 2.5, Common Polyatomic Ions). I recommend making flashcards and/or use Quizlet. Please keep your flashcards, as you will be tested on them throughout the entire year.
· There will be a test on the FIRST DAY OF SCHOOL on the polyatomic ions!
Part 2
Complete the practice test by the first day of class. There will be a test on this material within the first two weeks of school
