Dr. Alexander Yakushev, spokesperson of the experiment (right) and Dominik Dietzel, PhD student from Johannes Gutenberg Mainz University, work on the detector channel used to register the short-lived ...

Since element 99 - einsteinium - was discovered in 1952 at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) from the debris of the first hydrogen bomb, scientists have ...

Since element 99 -- einsteinium -- was discovered in 1952 from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is ...

On the periodic table, most elements have at least one stable form. But others have only unstable forms, all of which decay by emitting radiation and transforming into different elements until ...

A new chart for highly charged ions (HCIs) has been proposed, aiming to replicate the conventional periodic table’s ...

Elements heavier than uranium don’t exist naturally on Earth. Researchers make these massive elements at the end of the periodic table by smashing existing atoms together in particle accelerators.

The periodic table has been a vital foundational tool for material research since it was first created 150 years ago. Now, researchers add an entirely new dimension to the table, offering a new set of ...

Every field of science has its favorite anniversary. For physics, it’s Newton’s Principia of 1687, the book that introduced the laws of motion and gravity. Biology celebrates Darwin’s On the Origin of ...

A century and a half ago, a Russian chemistry professor published a classification of all the known elements, organized by atomic weight. Today, the system that he created for his students — plus some ...
