In nuclear physics, "magic numbers" are specific numbers of nucleons (protons or neutrons) that correspond to particularly stable configurations within atomic nuclei.; These numbers are believed to arise from the underlying shell structure of atomic nuclei. The heaviest known ‘magic’ nucleus is lead (82 protons).
