Deformed and unusually long-lived ones might be found in the Island of (*)Stability, and stable ones are said to have a magic number of constituents.
The stable radius of one of these structures is equal to 1.25 times their mass to the one-thirdpower. One theory of the structure of these objects describes how those with 2, 8, and 20 substituentsare unusually stable; that model is the shell model. Hyperfine splitting is caused by the magneticmoment of these entities. Deformed and unusually long-lived ones might be found in the Island of (*)Stability, and stable ones are said to have a magic number of constituents. Their binding energy can becalculated by finding the equivalent energy of their mass defects, and they are made of baryons heldtogether by the strong force. For 10 points, identify these structure which contains protons and neutrons andis surrounded by electrons, the center of an atom.
