Nuclear models are theoretical frameworks used to describe the structure and behavior of atomic nuclei. These models help scientists understand how protons and neutrons interact within the nucleus, influencing its stability and reactions. Common models include the Liquid Drop Model and the Shell Model, each providing unique insights into nuclear properties. By employing these models, researchers can predict nuclear phenomena such as decay rates and reaction pathways. Understanding nuclear models is crucial for advancements in fields like nuclear energy and medical imaging, where nuclear reactions play a significant role in technology and applications.
