The rock probably contains on the order of a few atoms of protactinium at any one time, as part of the complex decay chain of the uranium that makes up a much larger fraction of the sample. In no meaningful way is protactinium itself visible in the sample, but sadly that's about the ...

In December of 2002, this booklet was de-accessioned from the table: This is the first time I have ever parted with a sample, and may be the last, as it was something I did only after weeks of agonizing deliberation. The reason for parting with it was that I was offered, by a hig...
Heavier, unstable elements may exist elsewhere in the universe, like inside dense neutron stars, but scientists can study them here only by smashing together lighter atoms to make heavier ones and then sifting through the decay chain. “We really do not know what is the heaviest element that ...

After a few more steps in this decay chain, one of the nuclei produced is the isotope lawrencium 266—a nucleus with 103 protons and 163 neutrons that had never been seen before. Previously known isotopes of lawrencium have fewer neutrons, and are less stable. This novel species, however...
An overview of the up to date situation regarding SHEs is provided by the portion of the Chart of Nuclides of Fig.3, where all the produced isotopes are shown along with indication of their predominant decay modes and half-lives (see also a summary table in Appendix 1). ...
