! 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 isotopes have half-lives of at least four years (the longest-lived isotope in the gap is [[radon-222]] with a half life of less than four ''days''). Radium's longest lived isotope, at a notable 1600 years, thus merits the element's inclusion here.</ref> by [[Decay chain|decay chain]]
