Students use the terms isotope, atomic number, mass number, and atomic mass. Atomic Theory: Structure of the Atom: Students use the terms isotope, atomic number, mass number, and atomic mass to ...

For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based ...

An international research collaboration has provided experimental and theoretical evidence for the existence of the magic number of six in carbon isotopes. The researchers experimentally determined ...

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

All three isotopes of hydrogen have identical chemical properties. This is because the number of electrons determines chemical properties, and all three isotopes have one electron in their atoms. An ...

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 ...

Deuterium is a stable isotope of hydrogen, which, unlike “normal” hydrogen atoms, or protium, also contains a neutron. The isotope deuterium has one proton, one neutron and one electron. One out of ...

For the first time those little numbers that appear beneath some of the commonest elements in the periodic table boxes are about to change from a single value to an interval of numbers An ...

Artemis Spyrou receives funding from the National Science Foundation and the Department of Energy/National Nuclear Security Administration. When you hear the term “radioactive” you likely think “bad ...
