Matter is made up of very small particles called ____________.

Options

A. Substances
B. Molecules
C. Gases
D. Pattern

Answer

**Step-by-Step Solution:**

1. **Understanding Matter**: The question asks about what matter is made up of. Matter is anything that has mass and occupies space.

2. **Identifying the Small Particles**: We know that matter is composed of very small particles. These particles are fundamental building blocks of all substances.

3. **Recognizing the Terms**: The two main types of small particles that make up matter are "atoms" and "molecules". Atoms are the smallest units of an element, while molecules are formed when two or more atoms bond together.

4. **Choosing the Correct Answer**: The question specifically asks for the term that describes the very small particles that make up matter. The correct answer is "atoms" or "molecules". However, since the question format suggests a singular answer, we can conclude that "atoms" is the most appropriate term to fill in the blank.

5. **Final Answer**: Therefore, the complete statement is: "Matter is made up of very small particles called **atoms**."
