What is the value of charge on an electron?

Options

A. 1.6x10^(-19) C
B. -1.6x10^(-19) C
C. -1.6x10^(19) C
D. -1.6x10^(-29) C

Answer

To find the value of the charge on an electron, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Charge**:
- The charge is a fundamental property of matter. Electrons are subatomic particles that carry a negative charge.

2. **Identify the Charge of an Electron**:
- The charge of an electron is a well-established constant in physics. It is known to be negative.

3. **State the Value**:
- The value of the charge on an electron is approximately \( -1.6 \times 10^{-19} \) Coulombs.

4. **Units**:
- The unit of charge is the Coulomb (C). Therefore, when we express the charge of an electron, we write it as \( -1.6 \times 10^{-19} \, \text{C} \).

5. **Conclusion**:
- Based on the above information, we conclude that the charge on an electron is \( -1.6 \times 10^{-19} \) Coulombs.

### Final Answer:
The value of charge on an electron is \( -1.6 \times 10^{-19} \, \text{C} \).
