WebThe metal has about five synthetic isotopes with known half-life and the mass numbers ranging between 285 and 289. All of these are said to be unstable in nature, but 289Fl is considered as the most stable isotope of … In the late 1940s to early 1960s, the early days of making heavier and heavier transuranic elements, it was predicted that since such elements did not occur naturally, they would have shorter and shorter spontaneous fission half-lives, until they stopped existing altogether around element 108 (now called hassium). Initial work in synthesizing the heavier actinides seemed to confirm this. But the nuclear …
