Which of the following numbers are called magic numbers?

Options

A. `2, 8`
B. `2, 8, 18`
C. `2, 8, 18, 32`
D. `2, 8, 18, 27`

Explanation

To determine which numbers are called magic numbers, we need to understand the concept of magic numbers in the context of nuclear physics and chemistry.

### Step-by-Step Solution:

1. **Definition of Magic Numbers**: Magic numbers refer to specific numbers of protons or neutrons in the nucleus of an atom that result in a more stable configuration. These numbers are associated with complete shells of nucleons (protons and neutrons).

2. **Identifying Magic Numbers**: The commonly accepted magic numbers are:
- 2
- 8
- 20
- 28
- 50
- 82
- 126

3. **Understanding the Pattern**: The magic numbers indicate that nuclei with these numbers of protons or neutrons are more stable than those with non-magic numbers. This stability arises from the filled shells of nucleons.

4. **Listing the Options**: If the question provides multiple-choice options, we need to check which of the options include the recognized magic numbers.

5. **Selecting the Correct Option**: Based on the provided options, we identify which set of numbers includes the magic numbers listed above.

6. **Conclusion**: The correct option will be the one that includes the numbers 2, 8, 20, 28, 50, 82, and 126.
