The size of the nucleus is approximately

Options

A. `10^(18)` m
B. `10^(-10)` m
C. `10^(-8)` m
D. none of these

Answer

To determine the approximate size of the nucleus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to find the approximate size of an atomic nucleus from the given options.

2. **Recall the Size of the Nucleus**: The size of the nucleus is typically on the order of 10^-15 meters (or 1 femtometer). This information is based on experimental findings and theoretical models, particularly those proposed by Ernest Rutherford.

3. **Evaluate the Options**:
- Option 1: 10^18 meters
- Option 2: 10^-10 meters
- Option 3: 10^-8 meters
- Option 4: None of these

4. **Compare the Options with the Known Size**:
- 10^18 meters is much larger than the size of a nucleus.
- 10^-10 meters is more comparable to the size of an atom, not the nucleus.
- 10^-8 meters is also larger than the nucleus size.
- Since none of the options match the approximate size of the nucleus (10^-15 meters), we conclude that the correct answer is not listed.

5. **Final Conclusion**: The correct answer is Option 4: None of these.
