Question

classify the following diagram as diatomic molecules, polyatomic molecules, molecules that are compounds, molecules that are not compounds, or elemental forms of the substance. check all that apply.

□ diatomic molecules
□ polyatomic molecules
□ molecules that are compounds
□ molecules that are not compounds
□ molecules that are compounds
□ elemental form of the substance
□ none of the above

Explanation:

• Diatomic molecules: A diatomic molecule consists of two atoms. In the diagram, each molecule has two atoms (represented by two different - colored spheres), so it is not a diatomic molecule.
• Polyatomic molecules: A polyatomic molecule has more than two atoms. The molecules in the diagram have two atoms each, so it is not a polyatomic molecule.
• Molecules that are not compounds: A molecule that is not a compound is an elemental molecule. Since the molecules in the diagram are made of two different types of atoms (as indicated by different colors), they are compounds, not elemental molecules.
• Molecules that are compounds: A compound is a substance formed when two or more different elements are chemically bonded. The molecules in the diagram are made of two different types of atoms (different - colored spheres), so they are compounds.
• Elemental form of the substance: An elemental substance consists of only one type of atom. The molecules in the diagram have two different types of atoms, so it is not an elemental form.

Answer:

molecules that are compounds
