Ionic Bonding Puzzle Lab
Introduction
When metals and non-metals chemically react, the atoms will tend to form ions or
charged atoms. Ions form because electrons are either gained or lost. Metals will
generally form cations or positive ions, since they tend to donate electrons Non-metals
will form anions or negative ions, since they tend to accept electrons.
Activity
In this activity you will create models of ionic compounds and observe the chemical
formula of the binary molecules you have created. Your data will be recorded in a data
table or chart, similar to the one below for each compound you create.
Procedures:
1. Cut the puzzle pieces.
2. Organize them in two groups: anions (negative ions) and cations (positive ions).
3. Use the name on the puzzle pieces to pick the appropriate parts for the first
compound in the chemical compound table.
4. Glue the puzzle pieces that you picked on the result sheet to form the compound.
5. Determine the name of each compound you created.
6. Draw and fill out a Data Chart under the compound.
7. Repeat steps 3-6 to construct the compounds in the chemical compounds page.
