1. Activity #17
Modeling Molecules

2. Activity 17: Modeling Molecules
White Space ?:
Do you think every element can combine with another on the periodic table? Explain. (3 sentences)
You need colored pencils for this lab!!!
Challenge Question:
How do atoms combine to form molecules?
Background: Read p B31 and write down two facts.
Vocabulary:
Atom: tiny particles that make up everything
Compound: 2 or more elements combined together
Molecule: groups of atoms held together by chemical attractions
Chemical bond: chemical attractions that hold atoms together

3. Activity 17: Modeling Molecules
Notes:
Chemical bonds are formed when electrons are either shared between atoms or moved from one atom to another
Bonds are forces of attraction between atoms. They are not actually objects.

4. Activity 17: Modeling Molecules
Materials: Read over the list on p 32
Write down what element each color piece will stand for during the lab
Procedure: Read p B32 and B33 and write down what questions you have about the lab
Data: Use the Modeling Molecules Chart

5. Activity 17: Modeling Molecules
Analysis Questions: On page B33 answer questions #1-3, 5-7 (skip 4) Conclusion: Explain how atoms and elements make molecules? What role do chemical bonds play? Is it possible for all of the elements to connect with each other? Notes to Self: Make sure your drawings are colored and labeled properly!
