*UPDATED 4/19/2019* These Ionic Bonding manipulative puzzles should help both your kinesthetic and visual learners to grasp the concept of positive and negative ions and the exchange of electrons as ionic bonds. A happy cat and an angry ant help students to remember that cations are positively charged and anions are negatively charged.
The ionic pieces fit together like puzzles to help students visualize why certain numbers of ions come together to form complete compounds. The activity sheet walks students through some examples by having them construct the compounds using the manipulatives and then explains how to name and write the correct chemical formula for an ionic compound.
This resource now includes polyatomic and polyvalent ions for extension, as well as a sheet of blank cations and anions in case you or your students would like to make your own! A separate student sheet with a table is included so students can create, name, and write the formulas for many more ionic bonds using all of the monatomic, monovalent, polyatomic, and polyvalent ions!
I suggest having students work in groups of 2 or 3. You can laminate the ion pieces to make them more sturdy, but this is not necessary. I put the ions for each group in a sandwich bag.
The students should work in their groups to follow the directions for making various compounds, naming them, and writing their chemical formulas. On the back of the worksheet, there is a table so they get a lot of practice with the manipulatives. There are two quick reflection questions as well. A blank table is included so students can create their own ionic bonds using the monovalent and/or the polyatomic and polyvalent ionic puzzles!
Answer keys are provided.
Usually this activity solidifies the concept of ionic bonding for my students!
