Researchers at the University of Waterloo have produced experimental evidence that quantum-level effects can alter the ...

A new super-heavy element, temporarily called 117, may soon be making its way into the periodic table after being successfully created in a laboratory setting. Made up of 117 protons, the element ...

For now, they're known by working names, like ununseptium and ununtrium — two of the four new chemical elements whose discovery has been officially verified. The elements with atomic numbers 113, 115, ...

Scientists at Berkeley Lab have used a titanium beam to make atoms of element 116. Not only does this represent a new way to make the super rare element, but it stands as a proof-of-concept that they ...

If you've learned all the elements from actinium to zirconium, it's time to head back to the periodic table, where there's a new, extremely heavy element in town. In case you forgot your high school ...

Theory suggests that if physicists could cram just the right amount of stuff into a nucleus, the resulting element would hit a sweet spot. It could romp on the island of stability for days, months or ...

The rare radioactive substance made its way from the United States to Russia on a commercial flight in June 2009. Customs officers balked at accepting the package, which was ensconced in lead ...

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 ...
