Standard atomic weights, those numbers emblazoned under the elements on the periodic table, were once thought of as unchanging constants of nature. But researchers have tweaked the atomic weights of ...

Physicists have synthesized the element livermorium, which has the atomic number 116, using an unprecedented approach 1 that promises to open the way to new, record-breaking elements. The heaviest ...

TOKYO (Reuters) - Japanese scientists behind the discovery of element 113, the first atomic element found in Asia - indeed, the first found outside Europe or the United States - have dubbed it ...

Nineteen elements on the periodic table — including gold, cadmium, arsenic and aluminum — are getting their atomic weights adjusted. The International Union of Pure and Applied Chemistry (IUPAC) ...

For centuries, the quest for new elements was a driving force in many scientific disciplines. Understanding an atom's structure and the development of nuclear science allowed scientists to accomplish ...

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 ...

PTB’s ion traps (top right) and the PENTATRAP Penning trap mass spectrometer at MPIK in Heidelberg (bottom left) were used to obtain a new insight into the differences between isotopes and new limits ...

Whether you are an aspiring Chemistry student or just a normal know-it-all geek, the Periodic Table offers you the simplest way to keep tabs on the atomic elements and their chemical properties. And ...

Since the turn of the century, six new chemical elements have been discovered and subsequently added to the periodic table of elements, the very icon of chemistry. These new elements have high atomic ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...
