Activity #17 Modeling Molecules

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

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.

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

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!
