Shell Model of the Nucleus

The Shell Model of the nucleus describes protons and neutrons as occupying specific energy levels or "shells," similar to electrons in an atom. These particles move within the nucleus in patterned arrangements, with certain configurations providing more stability, much like closed shells in atomic physics. The model explains why some nuclei are more stable than others, based on how these nucleons fill the available energy levels. Overall, it offers a way to understand the structure and behavior of atomic nuclei by focusing on the arrangement of protons and neutrons within these shells.
