The expected location of the island of stability around Z = 112 (copernicium) is circled. [1] [2] In nuclear physics, the island of stability is a predicted set of isotopes of superheavy elements that may have considerably longer half-lives than known isotopes of these elements.
Superheavy elements, also ... The later nuclear shell model suggested that nuclei with about 300 nucleons would form an island of stability in which nuclei will be ...
Unbihexium has attracted attention among nuclear physicists, especially in early predictions targeting properties of superheavy elements, for 126 may be a magic number of protons near the center of an island of stability, leading to longer half-lives, especially for 310 Ubh or 354 Ubh which may also have magic numbers of neutrons.

By 1955, these elements were called superheavy elements. [8] The first predictions on properties of undiscovered superheavy elements were made in 1957, when the concept of nuclear shells was first explored and an island of stability was theorized to exist around element 126. [9]
Recently it has been shown that the multi-nucleon transfer reactions in collisions of actinide nuclei (such as uranium and curium) might be used to synthesize the neutron-rich superheavy nuclei located at the island of stability, [92] although formation of the lighter elements nobelium or seaborgium is more favored. [85]
A new study suggests that atoms could be stable at atomic number 164, which could help explain recent measurements of the ultradense asteroid 33 Polyhymnia.
Transuranic elements may be used to synthesize superheavy elements. [7] Elements of the island of stability have potentially important military applications, including the development of compact nuclear weapons. [8] The potential everyday applications are vast; americium is used in devices such as smoke detectors and spectrometers. [9] [10]
Science teachers will soon be instructing their pupils to buy new textbooks or crudely add four new elements to their copy of the periodic table. The chemical substances known as 113, 115, 117 and ...
