A. compound
B. Substance
C. Mixture
D. Element

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Definition of a Molecule:**
- A molecule is defined as the smallest particle of a substance that retains the chemical properties of that substance. It consists of two or more atoms that are chemically bonded together.

2. **Identifying the Composition of Molecules:**
- Molecules can be made up of the same type of atoms (like O2, which is made of two oxygen atoms) or different types of atoms (like H2O, which consists of two hydrogen atoms and one oxygen atom).

3. **Distinguishing Between Molecules and Compounds:**
- A molecule can be a simple molecule (like O2) or a compound (like H2O). A compound is a type of molecule that contains two or more different elements.
- For example, H2O is a compound because it consists of hydrogen and oxygen, which are different elements.

4. **Conclusion About Molecules:**
- Therefore, the molecule is indeed the smallest particle of a compound that retains the chemical properties of that compound.

**Final Answer:**
- The molecule is the smallest particle of a compound.
