1. Compound Manipulatives Assn. Make 15 models of ionic compounds. You may work with your lab group. Only 10 required if you work individually. For each compound, write the chemical formula and name. Use all 6 polyatomics Include monatomic ions of all the following charges. +1, +2, +3, -1, -2, -3 Label the charges and make a key for the elements. H = Blue O = White Cl = Yellow etc. Choose One: Use this assignment to be eligible to re-do the quiz Use this assignment as a one-day late work pass for a 10 point lab or assignment

2. Examples Fe (OH) 3 Iron (III) Hydroxide [Roman numeral showing +3 charge needed because Fe is a transition metal.] Na 2 SO 4 Sodium Sulfate NaNO 3 Sodium Nitrate

3. Drag the ions around to make compounds. Remember to balance the charges. Copy and paste the ions to make more. Al
