They are considered magical because historically, when the elements at these atomic numbers were observed, they seemed to have extraordinary stability than what the usual binding energy curve showed. If you are asking about the word "magic", it was a term coined by Wigner because he found this idea of shells too amazing but true.
Magic numbers in nuclear physics refer to specific numbers of protons or neutrons that result in increased stability of atomic nuclei. These magic numbers play a crucial role in determining the properties and behavior of atomic nuclei, such as their binding energy and nuclear structure. They help explain why certain elements are more stable than others and are important for understanding nuclear reactions and the stability of isotopes.
While they may have been called magic squares, there is absolutely nothing magical about them. The arrangement of numbers in magic squares is all very rational.
The second magic number in nuclear physics is 50. Nuclei with 50 protons or 50 neutrons tend to have increased stability, as they fill a complete shell of nucleons. This means that nuclei with proton or neutron numbers close to 50 often exhibit magic properties.
The Magic Numbers are from London, England.

Nuclear instability - a phenomenon concluded from empirical evidence. A model to explain this is based on the idea of nuclear shells. The number of protons and neutron in the nucleus. The nucleons fill up inside the nucleus in shells, each shell has a specific allotment of nucleons. incomplete shell gives rise to instability. The number of nucleons also affect the stability and such numbers are called 'magic numbers', 2, 8, 20, 28, 50, 82, 126. There are nuclides which have double the magic number, called 'double magic'. Magic and Double Magic numbers are charecterised by higher binding energies per nucleon for nuclides. The mechanism of stability may be calculated by using schroedinger's equation if the nuclear potential is known. in my opinion the instability and reason for randomness of decay may be due to vacuum fluctuations, connected to ideas from perturbation theory and definitely linked quantum field theory - any concrete mathematical evidence to support this is beyond me.
That every effect has a cause. There is no magic.
Nuclear shell models provide a useful framework for understanding the structure of atomic nuclei based on the organization of nucleons into energy levels, similar to electron shells in atoms. They successfully predict the magic numbers of stable nuclei and the nuclear binding energies. Additionally, shell models contribute to our understanding of nuclear properties such as spin, parity, and magnetic moments.
