  2. Isotopes of curium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_curium

    Curium (96 Cm) is an artificial element with an atomic number of 96. Because it is an artificial element, a standard atomic weight cannot be given, and it has no stable isotopes. The first isotope synthesized was 242 Cm in 1944, which has 146 neutrons. There are 19 known radioisotopes ranging from 233 Cm to 251 Cm. There are also ten known ...

  3. Curium - Wikipedia

    en.wikipedia.org/wiki/Curium

    All known isotopes of curium are radioactive and have small critical mass for a nuclear chain reaction. The most stable isotope, 247 Cm, has a half-life of 15.6 million years; the longest-lived curium isotopes predominantly emit alpha particles.

  5. List of radioactive nuclides by half-life - Wikipedia

    en.wikipedia.org/wiki/List_of_radioactive...

    This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.

  6. Fission products (by element) - Wikipedia

    en.wikipedia.org/wiki/Fission_products_(by_element)

    Se-79, half-life of 327k years, is one of the long-lived fission products.Given the stability of its next lighter and heavier isotopes and the high cross section those isotopes exhibit for various neutron reactions, it is likely that the relatively low yield is due to Se-79 being destroyed in the reactor to an appreciable extent.

  7. List of elements by stability of isotopes - Wikipedia

    en.wikipedia.org/wiki/List_of_elements_by...

    The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. This is a list of chemical elements by the stability of their isotopes. Of the first 82 elements in the periodic table, 80 have isotopes considered to be stable. [1] Overall, there are 251 known stable isotopes in ...
