Nuclear Chart with Neutron and Proton Numbers

This chart visually maps atomic nuclei based on their proton number (Z) and neutron number (N). It illustrates the 'valley of stability' where stable isotopes reside (black squares) and categorizes unstable nuclides by their primary decay modes, including beta-plus, beta-minus, alpha, proton, neutron emission, and spontaneous fission.
