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 ...

The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other ...

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 ...

Researchers used a particle accelerator and co-precipitation to study the chemical reactivity of single rutherfordium atoms. Such experiments will continue the advancement of relativistic chemistry ...

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 ...
