The conventional magic numbers are {2, 8, 20, 28, 50, 82, 126}. Magic number, in physics, in the shell models of both atomic and nuclear structure, any of a series of numbers that connote stable structure. The magic numbers for atoms are 2, 10, 18, 36, 54, and 86, corresponding to the total number of electrons in filled electron shells. In some cases there the isotopes can consist of magic numbers for both protons and neutrons; these would be called double magic numbers.

In nuclear physics, a magic number is a number of nucleons (either protons or neutrons) such that they are arranged into complete shells within the atomic nucleus.The seven most widely recognized magic numbers as of 2007 are 2, 8, 20, 28, 50, 82, and 126 (sequence A018226 in OEIS).Atomic nuclei consisting of such a magic number of nucleons have a higher average binding energy per nucleon than Thanks for the A2A. I will answer this question based on my domain. In mathematics, magic numbers are those which can be split into two pairs of two cubic numbers. Like 1729=10³+9³=12³+1³.

All such nuclei are particularly highly stable and are called "doubly magic". Lead-208 is one such example of a "doubly magic" nucleus as it has both 82 protons and 126 neutrons. Complicating the process is that magic numbers of either protons or neutrons—equivalent to the idea of closed electron shells in chemistry—make the nuclei more resistant to capturing further Nuclear Magic Numbers Last updated; Save as PDF Page ID 1483; Introduction; Isotope Stability; Magic Numbers; Unstable or Stable; References; Nuclear Stability is a concept that helps to identify the stability of an isotope. The two main factors that determine nuclear stability are the neutron/proton ratio and the total number of nucleons in Nuclear physics Not-so-magic numbers David Warner When a nucleus has a ‘magic’ number of neutrons or protons, it is particularly stable. But it seems that for exotic nuclei, with large numbers of neutrons relative to protons, these magic numbers can change.
