“I DISCOVER elements,” Glenn Theodore Seaborg once told an interviewer. And he certainly does: in less than 20 years. Chemist Seaborg shared in the discovery of nine new elements, all of them in the ...

Scientist whose research into transuranic elements revised the understanding of nuclear fission Darleane Hoffman’s research into superheavy radioactive elements at the University of California’s ...

Near the beginning of time, the universe almost certainly contained many elements heavier than uranium, the heaviest element that exists naturally on earth. Gradually these “transuranium” elements ...

We’ve reached the limit of a very successful way to make new elements in the lab. In new research, scientists unveil a new take on that technology and report its success. The heaviest elements could ...

Heavy elements: Researchers created molecules containing actinium (Ac) and Nobelium (No), atoms found on opposite sides of the actinide series of chemical elements. They expect chemical properties to ...

Using Lawrence Berkeley National Laboratory’s 88-Inch Cyclotron, an international team of physicists has successfully made two atoms of livermorium (atomic symbol Lv) using a titanium beam for the ...

Oct. 11, 1939. Europe is at war, and US president Franklin D. Roosevelt has just received a fateful letter from Albert Einstein. Noting that “the element uranium may be turned into a new and important ...

Researchers from the University of Liverpool are exploring the behaviors that occur at the limits of neutron and proton counts, aiming to determine where the periodic table of elements concludes. The ...

The fermium isotopes studied by laser spectroscopy are highlighted. Credit: S. Raeder Fermium studies indicate nuclear shell effects diminish as nuclear mass increases, emphasizing macroscopic ...
