Magic number in atomic physics

In atomic physics, "magic numbers" refer to specific numbers of protons or neutrons in an atomic nucleus that result in particularly stable configurations. These numbers are significant because nuclei with these counts tend to be less likely to undergo radioactive decay and are more stable than others. The magic numbers are typically 2, 8, 20, 28, 50, 82, and 126. This stability arises from the way particles are arranged within the nucleus, similar to how certain arrangements of people can create a more balanced and harmonious group.
