Which of these sub-atomic particles does not possess any electrical charge?

Options

A. Protons
B. Electrons
C. Neutrons
D. None of these

Answer

To answer the question "Which of these sub-atomic particles does not possess any electrical charge?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Sub-Atomic Particles**: The common sub-atomic particles are:
- Proton
- Electron
- Neutron
- Positron

2. **Determine the Charge of Each Particle**:
- **Proton**: Protons carry a positive charge (+1.6 x 10^-19 Coulombs).
- **Electron**: Electrons carry a negative charge (-1.6 x 10^-19 Coulombs).
- **Neutron**: Neutrons are electrically neutral, meaning they have no charge (0 Coulombs).
- **Positron**: Positrons are the antimatter counterparts of electrons and carry a positive charge (+1.6 x 10^-19 Coulombs).

3. **Identify the Particle with No Charge**: From the information above, we see that:
- Proton: Positive charge
- Electron: Negative charge
- Neutron: No charge (neutral)
- Positron: Positive charge

4. **Conclusion**: The sub-atomic particle that does not possess any electrical charge is the **Neutron**.

### Final Answer:
The sub-atomic particle that does not possess any electrical charge is the **Neutron**.
