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.
The chart of those nuclides is also known as a Segrè chart, after the physicist Emilio Segrè. [3] The Segrè chart may be considered a map of the nuclear valley. The region of proton and neutron combinations outside of the valley of stability is referred to as the sea of instability. [4] [5]
The island of stability is a hypothetical region in the top right cluster of nuclides that contains isotopes far more stable than other transuranic elements. There are no stable nuclides having an equal number of protons and neutrons in their nuclei with atomic number greater than 20 (i.e. calcium ) as can be readily observed from the chart.
The expected location of the island of stability. The dotted line is the line of beta stability. Moscovium is expected to be within an island of stability centered on copernicium (element 112) and flerovium (element 114).

"In nuclear physics, the island of stability is the prediction that a set of superheavy nuclides with magic numbers of protons and neutrons will temporarily reverse the trend of decreasing stability in elements heavier than uranium." -- I think this sentence is a subject to improvement.
I have updated the proton numbers along the Z axis to address the issue brought forth on the talk page. See the issue here: w:Talk:Island of stability #The diagram in the beginning of the article has wrong numbers in the Z(proton number) axis: 17:07, 23 June 2012: 842 × 431 (1.93 MB) InvaderXan
The unusual stability of isotopes having magic numbers means that transuranium elements could theoretically be created with extremely large nuclei and yet not be subject to the extremely rapid radioactive decay normally associated with high atomic numbers. Large isotopes with magic numbers of nucleons are said to exist in an island of stability ...
