Which of the following particles has no electric charge?

Options

A. proton
B. neutron
C. electron
D. ion

Explanation

To determine which of the following particles has no electric charge, we need to analyze the three main types of subatomic particles that make up an atom: protons, neutrons, and electrons.

### Step-by-Step Solution:

1. **Identify the Subatomic Particles**:
- The three main subatomic particles are:
- Protons (P)
- Neutrons (N)
- Electrons (e)

2. **Determine the Charge of Each Particle**:
- Protons are positively charged.
- Neutrons are neutral, meaning they have no charge.
- Electrons are negatively charged.

3. **Identify the Particle with No Charge**:
- From the information above, we can see that neutrons are the only subatomic particles that do not carry any electric charge.

4. **Conclusion**:
- Therefore, the particle that has no electric charge is **neutrons**.

### Final Answer:
The particle that has no electric charge is **neutrons**.
