The most recent elemental advance came last year when nuclear scientists at the Helmholtz Center for Heavy Ion Research in Germany bombarded a lump of 97 - proton berkelium with a beam of 20 - proton calcium ions.

More recently the radioisotope berkelium - 249 produced at HFIR was used to discover and then confirm the existence of element 117.

In the latest edition of the journal Science, Florida State University Professor Thomas Albrecht - Schmitt captures the fundamental chemistry of the element berkelium, or Bk on the periodic table.

Through this process, Albrecht - Schmitt found that that berkelium was very similar to its periodic table neighbor californium in its structure, but chemically it had some significant differences.

In a series of carefully choreographed experiments both at his specialized lab and at the FSU - based National High Magnetic Field Laboratory, Albrecht - Schmitt made a berkelium borate compound and a complex berkelium molecule in the form of crystals, and also completed a series of measurements of the element to better understand its structural and chemical similarities to surrounding elements such as californium (Cf) and Curium (Cm).

«The experimental results were hinting at this unusual behavior in berkelium, but there wasn't enough experimental evidence to say yes, 100 percent, this is what we're seeing,» says study co-author Wibe Albert de Jong, a CRD scientist.

Joseph Hamilton, a nuclear physicist at Vanderbilt University in Nashville, says that Oganessian asked for his help in getting a berkelium target from ORNL.

In fact, Rykaczewski says, the shipment was so well protected against radioactivity leakage that when it arrived at customs, fresh off the Delta flight, Russian officials didn't believe it was berkelium because they couldn't detect any radioactivity.

Once the paperwork was finally sorted, Oak Ridge researchers packed the berkelium in five separate barrels, each with a minuscule 4.4 milligrams of the stuff heavily shielded by lead.

The Dubna researchers were famous for their method of making calcium - 48, but they would need ORNL's help to get the berkelium - 249.

A team led by Yuri Oganessian of the Joint Institute for Nuclear Research in Dubna, Russia, reports smashing together calcium - 48 — an isotope with 20 protons and 28 neutrons — and berkelium - 249, which has 97 protons and 152 neutrons.

ORNL scientists let it all cool for three months and spent another three months painstakingly separating the berkelium from the californium.

And off the berkelium target went to Dubna, where late last year it helped make a brand - new element never before seen on Earth.

The tradition is that whichever lab makes a new element gets to suggest its name and hence we already have dubnium (element 105), darmstadtium (element 110), and berkelium (element 97) after the Lawrence Berkeley Laboratory, the third lab that has dominated the field of superheavy elements.

Albrecht - Schmitt and his research team have conducted similar work on the elements californium and berkelium.

«A few years ago, no one even thought you could make a berkelium compound.»

However, these simple rules do not apply when it comes to elements from berkelium and beyond because some of the electrons line up opposite of the way scientists have long predicted.
