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 ...

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 ...

The project is an opportunity for notable filmmakers, such as British Academy of Film & Television Arts award winner Issacs, to explore the human side of the periodic table. “We don’t pitch it as a ...

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 ...

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 ...

The atomic bombs dropped over Hiroshima and Nagasaki in Japan towards the end of World War II continues to divide opinion to this day. While one side argues that the use of these weapons hastened the ...
