For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, an isotope of the chemical element technetium (Tc). Electron capture decay ...

This year marks the 150th anniversary of the publication of Mendeleev’s Periodic Table of Chemical Elements in 1869. In celebration, the United Nations Educational, Scientific, and Cultural ...

Texas A&M researchers have unlocked a new way to harness astatine-211, a rare and powerful isotope that may revolutionize cancer treatment. Astatine is the rarest naturally occurring element on the ...

Chemists achieve synthetic feat with radioactive promethium for the first time. “It’s a tour de force,” says Polly Arnold, a chemist at Lawrence Berkeley National Laboratory in Berkeley, California, ...

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact, they ...

Whole new classes of compounds can be created from small clusters of atoms acting like single atoms of another element, researchers demonstrate for the first time in work reported in this week's ...
