This decay chain shows what happened when Japanese researchers created the elusive atomic element 113. The atom quickly decayed by shedding alpha particles consisting of two protons and two neutrons.

When Dmitri Mendeleev first put together the periodic table, he left blank spots for elements that weren’t yet discovered. He’d probably be quite surprised, however, to learn that we’ve now identified ...

(LiveScience) Scientists in Japan think they've finally created the elusive element 113, one of the missing items on the periodic table of elements. Element 113 is an atom with 113 protons in its ...

The most unambiguous data to date on the elusive 113th atomic element has now been obtained. A chain of six consecutive alpha decays, produced in experiments at the RIKEN Radioisotope Beam Factory ...

After nine years of painstaking experiment, researchers in Japan reported yesterday 1 that they have created a third atom of the element 113. That success, according to experts in the field, could see ...

The claim needs to be verified by chemical authorities, but the team says it's the strongest evidence yet for the highly unstable element. By Rebecca Boyle Published Sep 26, 2012 7:47 PM EDT Add ...

The seventh row of the periodic table of elements has finally been completed, thanks to a group of Japanese, Russian and American researchers. The new substances discovered still have no official ...

A group of Japanese scientists announced Wednesday that they have finally synthesized the elusive element 113, which has been called ununtrium. If confirmed, the feat would mark the first time ...

TOKYO (AP) — A team of Japanese scientists have met the criteria for naming a new element, the synthetic highly radioactive element 113, more than a dozen years after they began working to create it.

The most unambiguous data to date on the elusive 113th atomic element has been obtained by researchers at the RIKEN Nishina Center for Accelerator-based Science (RNC). A chain of six consecutive alpha ...
