Each electron present in an atom contains one unit of_________

Options

A. negative charge
B. positive charge
C. neutral charge
D. none of them

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what each electron in an atom contains in terms of charge.

2. **Identifying Atomic Particles**: In an atom, there are three main types of subatomic particles: protons, electrons, and neutrons.
- Protons carry a positive charge.
- Electrons carry a negative charge.
- Neutrons are neutral and carry no charge.

3. **Focusing on Electrons**: Since the question specifically mentions electrons, we need to focus on their properties.
- Each electron is known to carry a specific type of charge.

4. **Charge of an Electron**: Each electron contains one unit of negative charge. This is a fundamental property of electrons.

5. **Conclusion**: Therefore, the answer to the question is that each electron present in an atom contains one unit of negative charge.

**Final Answer**: Each electron present in an atom contains one unit of negative charge.
