This week's element is neptunium, which has the atomic symbol Np and atomic number 93. Neptunium was named for the planet Neptune, the next planet away from the sun after Uranus (which was uranium's ...

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 ...

Uranium and plutonium have gotten famous, or infamous, because they are used in atom bombs. We could have been saying that about another material—one that few actually know. Learn about the material ...

Awarded a prestigious Department of Energy Office of Science Graduate Student Research award, University of Iowa graduate student Logan Augustine will head to the Los Alamos National Laboratory to ...

image: Electron micrographs show neptunium dioxide grain size increases with increasing temperature. Processing the material at higher temperature increases its grain size and reduces its movement ...

Scientists from The University of Manchester have managed to successfully make a transuranium complex where the central metal, here neptunium, forms a multiple bond to just one other element. Enabling ...

A century ago, the periodic table looked much different than it does today. It had empty spots for elements that had not yet been found, and ended at uranium (element 92), the heaviest known element ...

DELIVERING this year's Harrison Howe Lecture on November 18 to the Rochester Section of the American Chemical Society, Prof. G. T. Seaborg referred to the importance which the newly discovered ...
