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.

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 ...

Since it was first synthesized in a post-WW2 American lab in 1949, berkelium has been a rebel of the periodic table, defying ...

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, ...

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.

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.

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 ...

It features a berkelium atom sandwiched between two eight-membered carbon rings. This symmetrical structure was confirmed ...

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.

Scientists have discovered 'berkelocene,' the first organometallic molecule to be characterized containing the heavy element berkelium. The breakthrough disrupts long-held theories about the ...

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, ...
