1. Garside Spring 2012

2. Discussion Regarding Reactions Lab You need to remember your 7 Diatomic Elements! Be sure to put brackets around your polyatomic ions when in a compound – Example: Mg(OH) 2 You do not need to use the crisscross rule for molecular formulas!! Remember – covalent bonds! Remember to include roman numerals in the names of multivalent compounds

3. What Will I Be Given on Friday? What Will I Need to Memorize? Polyatomic Chart (Table 3) The 7 Diatomic Elements Solubility Chart Periodic Table

5. Instructions: Write your answers to the following questions on a lined piece of paper. You can use ALL of your notes to help you. After every 10 questions, I will post the answers. You will have an opportunity to mark / correct your work before we move on to the next 10. We will only go through one round TODAY Once the activities are over, you will have an opportunity to choose a worksheet or textbook questions to work on for the remainder of the period based on your needs.
