With these elements, the atomic weight of the longest-lived isotope gets listed on the periodic table, according to the International Union of Pure and Applied Chemistry (IUPAC).

More accurately, every element on the periodic table has unstable isotopes. “Isotope” is the word for different versions of the same element with different numbers of neutrons. For example, a ...

The periodic table currently has 118 chemical elements (SN: 11/30/16).The five heaviest elements were all produced using a beam of calcium-48. That’s a variety, or isotope, of calcium with 28 ...

Carolyn Krause presents the second part of the three-part series on the Oak Ridge National Laboratory's role in the discovery of elements in the periodic table. Many of them have been synthesized ...

The new machines are much better at this and can handle elements at the heavier end of the periodic table, like ytterbium-176, which is used in nuclear medicine and radiology.

Currently, there are 118 known elements on the periodic table, from hydrogen all the way to oganesson, which was officially named in 2016. It’s pretty hefty, with at least 294 subatomic ...

Certain elements have more than one stable isotope. For instance, carbon has two — carbon-12 and carbon-13. (The numbers in each isotope reveal how many particles they have in their nuclei ...

“The periodic table is something fundamental,” says Witold Nazarewicz, a theoretical nuclear physicist and chief scientist at the Facility for Rare Isotope Beams at Michigan State University.
