! colspan="4" | [[Chemistry:Actinide|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 [[Chemistry:Polonium|polonium]] (84) where no nuclides have half-lives of at least four years (the longest-lived nuclide in the gap is [[Physics:Radon-222|radon-222 w]]ith a half life of less than four ''days''). Radium's longest lived isotope, at 1,600 years, thus merits the element's inclusion here.</ref> by [[Physics:Decay chain|decay chain]]

}}<br />"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 Bk<sup>248</sup> with a half-life greater than 9&nbsp;y. No growth of Cf<sup>248</sup> was detected, and a lower limit for the β<sup>−</sup> half-life can be set at about 10<sup>4</sup>&nbsp;y. No alpha activity attributable to the new isomer has been detected; the alpha half-life is probably greater than 300&nbsp;y."</ref>
