Covalent bonds are much stronger than ionic ones. Based on the Lewis structures you created, why do you think this is? 3. Metals do not participate in covalent bonds. Explain why. 4. What determines whether an atom forms a positive or negative charge in an ionic bond? 5. Could you have a compound with the formula HS3? Why or why not? 1. 2. What’s Going On? The valence, or outer shell electrons, of an atom determine how they participate in reactions with one another. Atoms bond to gain stability by © 2011 Facts on File.
C. Ion Exchange Resin Treatment 1. Place a piece of filter paper in the top of a funnel and fill the funnel with ion exchange resin beads. 2. Place the funnel over a large beaker. 3. Measure 200 ml of hard water and pour it slowly into the funnel containing resin beads. 4. Allow the water to filter through the resin and collect the softened water from the large beaker. Set aside the beaker of water for procedure step 5. Measure 2 ml of the softened water from each procedure and repeat the foaming action test from step 1.
