In nuclear physics, a magic number is a number of nucleons, either protons or neutrons, that are arranged into complete shells within the atomic nucleus. These numbers are crucial for the stability of atomic nuclei, as they indicate the number of filled nuclear shells. The Octet Rule, formulated from the observation that atoms with eight valence electrons are especially stable, also applies to nuclei.
Magic numbers are a series of numbers that connote stable structure in both atomic and nuclear shell models. They are based on the four quantum numbers that identify states. The nuclear magic numbers correspond to filled shells and are defined as the number of nucleons required for the completion of the energy levels of the nucleus. Nuclei with a proton number or neutron number equal to certain numbers, such as 2,8,20,28,50,82, and 126, behave in a way that is more stable than other elements.
Physicists refer to the number of protons or neutrons in a full shell as “magic” numbers, with numbers 2, 8, 20, 28, 50, 82, and 126 widely used. Magic numbers represent a shell being completely filled, requiring additional nucleons to fill it.

What is magic in physics?
In nuclear physics, a magic number is a number of nucleons arranged into complete shells within the atomic nucleus, making them more stable than other nuclei. The seven most widely recognized magic numbers as of 2019 are 2, 8, 20, 28, 50, 82, and 126. These numbers correspond to elements like helium, oxygen, calcium, nickel, tin, lead, and unbihexium, with 126 being only known for neutrons. Atomic nuclei with a magic number of nucleons have a higher average binding energy per nucleon, making them more stable against nuclear decay.
The unusual stability of isotopes with magic numbers allows transuranium elements to be created with extremely large nuclei without being subject to the rapid radioactive decay typically associated with high atomic numbers. Large isotopes with magic numbers exist in an island of stability, where theoretical calculations predict nuclei in this island are deformed.
What are the magic numbers 2 8 20 28 50 82 126?
Magic numbers are a crucial element in the physics of nuclei, representing a shell being filled with nucleons, requiring them to enter a higher shell. Conventional magic numbers are (2, 8, 20, 28, 50, 82, 126). They are found by comparing stable isotopes for different proton numbers and the number of stable nuclides with the same neutron numbers for neutrons. Incremental binding energies (IBE) also provide a stronger indication of magicality, as they indicate the binding energy of a nuclide with n neutrons and p protons.
Why 7 is a magic number?
The number seven is often associated with the divine soul, the pure spirit, and the great explorer. It represents perfecting human nature by joining the Holy Trinity and Earthly Elements, reconciling the physical and spiritual realms. The number seven is also the number of the pyramid, formed by a triangle on a square base. People with the number seven are considered mystic, excellent thinkers, idealists, and explorers. They are meditative, intuitive, sensible, and prone to magical forces, thinking, and codes. They understand human nature and are not deceived by appearances.
Why is 137 a magic number?
The number 137 is not only significant to scientists but also holds significance in Jewish mysticism, as it appears frequently in the Torah and signifies the lifespan of figures like Ishmael and Levi.

The nuclear magic number refers to the numbers that deal with the properties of protons and neutrons, as well as electrons and their interactions. It is a group of nucleons arranged in complete shells within their atomic nucleus, making them more stable than other nuclei. The seven widely recognized magic numbers in 2019 are 2, 8, 20, 28, 50, 82, and 126. Protons typically correspond to elements like oxygen, helium, nickel, calcium, tin, lead, and unbihexium.
The atomic nuclei with a magic number have an average binding energy that is higher per nucleon than expected, making them more stable against nuclear decay. Isotopes with magic numbers have exceptional stability, allowing transuranium elements to be theoretically created with larger-sized nuclei without being subjected to rapid radioactive decays.
The magic number is named after the inside of an atomic nucleus, where neutrons and protons are arranged in shell structures similar to the electron shell surrounding an atom. When filled with 2, 8, 20, 28, 50, and 82, 126 nucleons, they form a spherical shape. However, when the number of nucleons does not form a magic number, the nuclei lose their spherical shape and deform.

📹 The magic numbers in nuclear physics
What are the magic numbers in nuclear physics the answer is probably going to surprise you and to explain it it helps to start off …
Naturally, it is theoretically difficult to change the electron configuration..but not impossible if enough energy is involved correct? I believe there is enough energy involved inside our unnatural enriched fueled reactors which is why most, but not all, the actinides series isn’t found in nature in any measurable quantities. Gas phase discharges occur on a routine basis around the world, especially during fuel changes. So while technically you are correct in terms what would occur naturally in our world built from that periodic table, but that all changes when we change the natural ratio many times over and create the unnatural energy that doesn’t normally occur in turn doing things to our world we have yet to begin to discover and comprehend.
