Lawrence Livermore scientists, in conjunction with international researchers, have discovered five new atomic nuclei to be added the chart of nuclides. The study, conducted this fall, focuses on ...

Novel calculations have enabled the study of nearly 700 isotopes between helium and iron, showing which nuclei can exist and which cannot. Scientists report how they simulated for the first time using ...

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 ...

To discover superheavy elements and study their properties, we need to know the masses of the isotopes of elements heavier than uranium. Weighing these isotopes in an electromagnetic trap has now ...

There are 118 elements. Each element is unique by virtue of the different numbers of electrons, protons, and neutrons its atoms contain. Isotopes are atoms of a given element that vary only in the ...

While studying the atoms of heavy elements, physicists in Japan discovered a previously unknown isotope of uranium, with atomic number 92 and mass number 241, i.e. uranium-241. The finding refines our ...

Atomic nuclei are held together by the strong interaction between neutrons and protons. About ten percent of all known nuclei are stable. Starting from these stable isotopes, nuclei become ...

Scientists from Massey University in New Zealand, the University of Mainz in Germany, Sorbonne University in France, and the Facility for Rare Isotope Beams discuss the limits of the periodic table ...
