Nuclear Shell Model
The Nuclear Shell Model is a theoretical framework used to understand the structure of atomic nuclei. It likens the arrangement of protons and neutrons within a nucleus to how electrons are organized around an atom. In this model, nucleons (protons and neutrons) occupy different energy levels or "shells," similar to how electrons fill shells in an atom. This helps explain why certain nuclei are more stable than others, as filled shells correspond to stable configurations. The model successfully accounts for various nuclear properties, including energy levels and the occurrence of magic numbers, which are specific numbers of nucleons that result in particularly stable nuclei.

The nuclear shell model is a theoretical framework that describes the arrangement of protons and neutrons within an atomic nucleus. Similar to how electrons occupy specific energy levels around an atom, protons and neutrons fill "shells" in the nucleus. Each shell can only hold a certain number of particles, and when a shell is filled, a new one begins to fill. This model helps explain the stability of certain isotopes and the structure of nuclei, as well as phenomena like nuclear reactions and the behavior of radioactive elements.
