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 ...

It’s been 77 years since nuclear chemist Glenn T. Seaborg grouped and named the actinides —the 15 metallic elements on the periodic table with atomic numbers from 89-103, actinium through lawrencium.

Understanding how a small, gas-phase molecule containing an actinide atom reacts with other molecules helps us better understand the chemistry of heavy elements. These elements are often available in ...

More than 75 years after its initial discovery, scientists have created an organometallic molecule containing the transuranium element berkelium. According to a new study, the electronic signature of ...

Chemists have recently explored protactinium's multiple resemblances to more completely understand the relationship between the transition metals and the complex chemistry of the early actinide ...

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 ...

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 ...

Our understanding of the bonding, reactivity and electronic structure of actinides, though it has both fundamental and practical importance, lags behind that of the rest of the periodic table. A ...

Scientists from UB and the Department of Energy’s Lawrence Berkeley National Laboratory have discovered “berkelocene,” the first organometallic molecule to be characterized containing the heavy ...

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 ...
