! colspan="4" | [[Actinide]]s<ref>Plus radium (element 88). While actually a sub-actinide, it immediately precedes actinium (89) and follows a three-element gap of instability after [[polonium]] (84) where no nuclides have half-lives of at least four years (the longest-lived nuclide in the gap is [[radon-222]] with a half life of less than four ''days'').

}} "The isotopic analyses disclosed a species of mass 248 in constant abundance in three samples analysed over a period of about 10 months. This was ascribed to an isomer of Bk248 with a half-life greater than 9 [years]. No growth of Cf248 was detected, and a lower limit for the β− half-life can be set at about 104 [years]. No alpha activity attributable to the new isomer has been detected; the alpha half-life is probably greater than 300 [years]."</ref>
