The radius of an atomic nucleus is of the order of

Options

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

Explanation

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

### Step 1: Understand the Structure of an Atom
An atom consists of a nucleus at its center, which contains protons and neutrons, surrounded by electrons in various energy levels. The nucleus is much smaller than the overall size of the atom.

**Hint:** Remember that the nucleus contains most of the atom's mass but occupies a very small volume compared to the entire atom.

### Step 2: Know the Size of Atomic Nuclei
The radius of an atomic nucleus is typically on the order of 1.5 x 10^-13 cm to 6.5 x 10^-13 cm. This range is significantly smaller than the radius of an atom, which is about 10^-8 cm.

**Hint:** Compare the sizes of the nucleus and the atom to understand how small the nucleus is.

### Step 3: Identify the Correct Range
Given the options, we need to identify which one corresponds to the radius of an atomic nucleus. The correct range for the radius of a nucleus is in the order of 10^-13 cm, often referred to in units of Fermi (1 Fermi = 10^-15 m).

**Hint:** Look for options that are in the range of 10^-13 cm to find the correct answer.

### Step 4: Conclusion
Based on the information provided, the radius of an atomic nucleus is indeed of the order of 10^-13 cm.

**Final Answer:** The radius of an atomic nucleus is of the order of 10^-13 cm.
