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 ...

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 ...

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 ...

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 ...

Scientists at Berkeley Lab have used a titanium beam to make atoms of element 116. Not only does this represent a new way to make the super rare element, but it stands as a proof-of-concept that they ...
