The radius of an atomic nucleus is of the order of:

Options

A. `10^(10)m`
B. `10^(-13)m`
C. `10^(-15)m`
D. `10^(-8)m`

Explanation

To determine the order of the radius of an atomic nucleus, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of an Atom**:
- An atom consists of a central nucleus surrounded by electrons. The nucleus contains protons and neutrons.

2. **Identifying the Size of the Nucleus**:
- The nucleus is significantly smaller than the overall size of the atom. While the atom itself can be on the order of angstroms (10^-10 meters), the nucleus is much smaller.

3. **Establishing the Order of Magnitude**:
- The radius of an atomic nucleus is typically measured in femtometers (fm), where 1 femtometer = 10^-15 meters.

4. **Conclusion**:
- The radius of an atomic nucleus is of the order of 10^-15 meters.

5. **Selecting the Correct Option**:
- Based on the information provided, the correct answer is that the radius of an atomic nucleus is approximately 10^-15 meters.

### Final Answer:
The radius of an atomic nucleus is of the order of \( 10^{-15} \) meters.
