Merdeka.com – In nuclear physics, a magic number or number is a number of nucleons (either protons or neutrons, separately) such that they are arranged into complete shells in the atomic nucleus.

As a result, atomic nuclei with a ‘magic’ number of protons or neutrons are much more stable than other nuclei. The magic numbers for atoms are 2, 10, 18, 36, 54, and 86, corresponding to the total number of electrons in the filled electron shell.

The number of electrons present in the neutral atoms that make up the relatively unreactive noble gases is exactly the same as the atomic magic number. The magic numbers for the core are 2, 8, 20, 28, 50, 82, and 126.

In the nucleus, this increased stability occurs when there is a large energy gap between a series of filled energy levels and the next empty level. Here’s a complete description that is interesting for you to know.
