Which of these components of an atom has a positive charge?

Options

A. Electron
B. Neutron
C. Nucleus
D. Proton

Answer

To determine which component of an atom has a positive charge, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of an Atom**:
- An atom consists of a nucleus and an outer region where electrons are found. The nucleus contains protons and neutrons.

2. **Understand the Charges of Subatomic Particles**:
- Protons: These are positively charged particles found in the nucleus.
- Neutrons: These are neutral particles (no charge) also found in the nucleus.
- Electrons: These are negatively charged particles that orbit around the nucleus.

3. **Analyze the Question**:
- The question specifically asks which component has a positive charge.

4. **Evaluate Each Component**:
- Protons: As stated, protons have a positive charge.
- Neutrons: Neutrons have no charge (neutral).
- Electrons: Electrons have a negative charge.

5. **Conclusion**:
- Since protons are the only particles listed that have a positive charge, the answer to the question is protons.

### Final Answer:
The component of an atom that has a positive charge is **protons**.
