Flerovium - Periodic Table - Atomic Number - Mass - Radius

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 … WebThere are four known isotopes of flerovium with mass numbers 286-289.
