Calculate the charge on an alpha particle. Given on a proton`=1.6xx10^(19) C`.

Answer

To calculate the charge on an alpha particle, we need to understand its composition and the charge of its constituent particles.

### Step-by-step Solution:

1. **Identify the Composition of an Alpha Particle**:
An alpha particle is made up of 2 protons and 2 neutrons. The neutrons do not carry any charge, while protons carry a positive charge.

2. **Charge of a Proton**:
We are given that the charge of a proton (denoted as \( e \)) is \( 1.6 \times 10^{-19} \) coulombs.

3. **Calculate the Total Charge of the Alpha Particle**:
Since an alpha particle has 2 protons, the total charge \( Q \) of the alpha particle can be calculated as:
\[ Q = \text{Number of protons} \times \text{Charge of one proton} \]
Substituting the values:
\[ Q = 2 \times (1.6 \times 10^{-19} \, \text{C}) \]

4. **Perform the Calculation**:
\[ Q = 3.2 \times 10^{-19} \, \text{C} \]

5. **Conclusion**:
The charge on an alpha particle is \( 3.2 \times 10^{-19} \) coulombs.
