Chart of nuclei
Chart of nuclei (element or proton number Z versus neutron number N): stable nuclei along the valley of stability are shown in black, isotopes that have been detected at least once on Earth are shown in blue, and the large terrain of unknown nuclei is shown in red. The estimated paths for the r- and rp-processes for explosive nucleosynthesis in the cosmos are indicated by solid lines
