1. Check the boxes to indicate whether each model shows atoms, molecules, elements, and/or compounds.
- A: Atom ✓, Molecule ✓, Element ✓, Compound ✓
- B: Atom ✓, Molecule ✓, Element ✓, Compound ✓
- C: Atom ✓, Molecule ✓, Element ✓, Compound ✓
- D: Atom ✓, Molecule ✓, Element ✓, Compound ✓
- E: Atom ✓, Molecule ✓, Element ✓, Compound ✓
- F: Atom ✓, Molecule ✓, Element ✓, Compound ✓
2. Which models have molecules? Support your answer with details from the models.
- Models A, B, C, D, E, and F all have molecules because each contains particles made of two or more atoms bonded together, as shown by the connected circles representing chemical bonds.
3. Can an element be made of molecules? Support your answer with details from the models.
- Yes, an element can be made of molecules. For example, Model B shows multiple identical yellow spheres bonded in pairs, representing a diatomic molecule of a single element (like O₂ or N₂). Since all atoms are the same type and bonded together, it is both a molecule and an element.
