3Directions:
1. At each station, there are index card with three or more molecular formulas and
materials to make each molecular model.

(Metal + Non-Metal) = Ionic Bond & (Non-Metal + Non-Metal) = Covalent Bond
Analysis:
1. What do the holes in the model represent?
2. What is the difference between an Ionic Bond and a Covalent bond?
3. How can you predict if a bond will be ionic or covalent by using the
periodic table?
4. What is an Isomer?
Conclusion:
Write 2-3 sentences on what you learned by doing this activity.
