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 ...

Elements heavier than uranium don’t exist naturally on Earth. Researchers make these massive elements at the end of the periodic table by smashing existing atoms together in particle accelerators.

Fluorine is the most chemically reactive element on the periodic table. Only one isotope of fluorine occurs naturally. Researchers discovered a new isotope with four neutrons removed from the proton ...

What comes to mind when you think about isotopes? Radioactivity, perhaps? That’s only the tip of the iceberg. A new interactive periodic table of the elements and isotopes, launched last month by the ...

In creating five new isotopes, an international research team working at the Facility for Rare Isotope Beams (FRIB) at Michigan State University has brought the stars closer to Earth. The universe is ...

For new, human-made heavy elements on the periodic table, being “too ‘big’ for your own good” often means instability and a fleeting existence. The more protons and neutrons scientists squeeze ...

The very first element on the Periodic Table may be the key to solving mysteries hiding inside the atom’s nucleus. Nuclear ...

Provided by the International Atomic Energy Agency (IAEA), the Isotope Browser app is a useful chemistry resource that provides information on over 4,000 chemical isotopes (or “nuclides,” if one is ...

Measurements of an artificial radioactive element called lawrencium could revive an arcane controversy over the element’s position in the periodic table — and the structure of the table itself. An ...

For years, physicists have mapped the stability of atomic nuclei with remarkable confidence. The periodic table, with its ...
