Magic numbers refer to specific numbers of protons and neutrons in an atomic nucleus that confer extra stability. These numbers are 2, 8, 20, 28, 50, 82, and 126, and when a nucleus has a proton or neutron number equal to any of these, it is considered more stable than nuclei with other numbers of protons or neutrons.
