This list of nuclides shows observed nuclides that either are stable or, if radioactive, have half-lives longer than one hour. This represents isotopes of the first 105 elements, except for elements 87 (francium), 102 (nobelium) and 104 (rutherfordium). At least 3,300 nuclides have been experimentally characterized[1] (see List of radioactive nuclides by half-life for the nuclides with decay half-lives less than one hour).
A nuclide is defined conventionally as an experimentally examined bound collection of protons and neutrons that either is stable or has an observed decay mode.
