A handful of asteroids in our solar system are so dense that no element on Earth can explain their properties. Instead, they may be made of naturally occurring "superheavy elements" beyond those ...

Have we reached the end of the line of discoverable elements? Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered ...

For new, human-made heavy elements on the periodic table, being “too ‘big’ for your own good” often means instability and a fleeting existence. The more protons and neutrons scientists squeeze ...

OAK RIDGE, Tenn. — Tennessee, whose scientists played a key role in the discovery of a series of new super-heavy elements, is being rewarded with its name as part of one of the elements, Tennessine.

Carolyn Krause presents the second part of the three-part series on the Oak Ridge National Laboratory's role in the discovery of elements in the periodic table. Many of them have been synthesized ...

Actinides are a group of heavy, radioactive elements that include uranium, plutonium, americium, curium, berkelium and californium. Understanding how these elements bond with other atoms (known as ...

Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests. When you purchase through ...
