Plutonium (Pu) exhibits one of the most diverse and complex chemistries of any element in the periodic table. Since its discovery in 1940, scientists have synthesized and studied many different types ...

A team of scientists has discovered a new, stable form of plutonium – and done so by accident. The famously unstable element is tricky to transport, store and dispose of, but the find could lead to ...

The rare form of the element found on the Pacific seabed points to its violent birth in colliding stars. By William J. Broad Scientists studying a sample of oceanic crust retrieved from the Pacific ...

Elements that do not exist in nature—that have been created in a laboratory—are unstable. After hours or days of one element bombarding another with enough energy for both to fuse, the resulting new ...

Oxidation is the process where atoms lose electrons during a chemical reaction. Among the radioactive elements, neptunium and plutonium are much harder to oxidize than uranium. To study these elements ...
