Highly radioactive, berkelium is not only difficult to handle, but difficult to get a hold of. The team had to put in a request to the Oak Ridge National Laboratory in Tennessee, ...

Isotopesof berkelium. There are 14 known isotopes of berkelium, ranging from mass number 238 to 251. Berkelium’s most stable isotope is 247 Bk, which has a half-life of about 1,389 years.

Luckily, the team successfully trapped a berkelium atom between two cyclooctatetraene (COT) ligands, which Chemistry World describes as a kind of “organometallic sandwich.” What makes ...

Probing electronic structure in berkelium and californium via an electron microscopy nanosampling approach. Nature Communications , 2021; 12 (1) DOI: 10.1038/s41467-021-21189-1 Cite This Page : ...

PALCA: After returning to JFK, the berkelium set off again, with shipping papers. According to Rykaczewski, this time the customs agents said, yes, the papers are in order.

More than 75 years after its initial discovery, scientists have created an organometallic molecule containing the transuranium element berkelium. According to a new study, the electronic signature ...

Berkelium was discovered by acclaimed UC Berkeley chemist and pioneering nuclear medicine pioneer Glenn Seaborg in 1949 and remains one of the rarest synthetic elements in the world.

Berkelium, for example, was first synthesized at the University of California, Berkeley. “We’ve never discussed names because it’s sort of like bad karma,” she said.

It is a sandwich with the rarest of fillings. Researchers have unveiled berkelocene, a compound containing the synthetic element berkelium nestled neatly between two ring-shaped molecules (Science ...

Currently, berkelium’s primary use is in heavy element research. For example, its most stable isotope , Bk-249, played a significant role in the creation of superheavy element 117, tennessine.

Calcium has 20 protons and berkelium has 97, making for 117 protons total, the number found in tennessine’s nucleus. Combine calcium with the next element down the table, ...

The berkelium-249 and californium-249 chloride starting materials were supplied by the Isotope Program within the Office of Science. This work was supported by the U.S. Department of Energy ...
