To solve the problem, we need to identify which of the given options are created when atoms join together chemically and are made up of different atoms. 1. **Elements**: An element is a pure substance that cannot be broken down into simpler substances by chemical means. Elements consist of only one type of atom. Therefore, elements do not fit the description provided in the question. 2. **Atoms**: Atoms are the basic units of matter and the defining structure of elements. They are not created by the joining of other atoms; rather, they are the building blocks of matter. Thus, atoms do not fit the description either. 3. **Molecules**: Molecules are formed when two or more atoms join together chemically. They can consist of the same type of atoms (like O₂) or different types of atoms (like H₂O). Since the question specifies that the entities are made up of different atoms, molecules fit the description perfectly. Based on this analysis, the correct answer is: - \( \square \) elements (not applicable) - \( \square \) atoms (not applicable) - \( \square \) molecules (applicable) Thus, the only option that applies is **molecules**.
