The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ...
Researchers used supercomputers and statistics to predict properties of the heavy nucleus lead-208, consisting of 126 neutrons (red spheres) and 82 protons (blue spheres). The excess neutrons form a ...
Researchers may have just spotted the elusive, ephemeral nucleus of nitrogen-9 for the first time. With seven protons and two neutrons, the lopsided atomic nucleus of nitrogen-9 pushes the limits of ...
