What makes berkelium interesting compared to other actinides is that it has a tetravalent oxidation state (a positive charge of +4) that’s stabilized by the berkelium–carbon bonds.

The discovery of a metal-rich star packed with both light and heavy elements hints at exotic stellar explosions and the role of ancient dwarf galaxies in seeding the cosmos with uranium and thorium.

Berkelium is one of 15 actinides in the periodic table's f-block. One row above the actinides are the lanthanides. The pioneering nuclear chemist Glenn Seaborg discovered berkelium at Berkeley Lab ...

Only a Few Grams of This Element Exist—and Scientists Have Used It to Break the Rules of the Periodic Table. ... which is located above actinides in the periodic table.

Last week, we explored the evolution of the periodic table, with all its elements in order. Now that we’re well-organized, let’s dive into the reasoning.

This discovery marks a significant leap in understanding the chemical behavior of heavy actinides and challenges “long-held ...

The elements were placed in the periodic table’s seventh row, which is above the row of lanthanides and the row of actinides. In the 1980s and 1990s, Roberto noted, scientists at the GSI Helmholtz ...

In December 1949, University of California at Berkeley chemist Glenn Seaborg, along with Stanley Thompson and Albert Ghiorso, bombarded an isotope of the actinide americium, only discovered five ...
