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 ...

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 ...

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 ...

As of 2019, the Periodic Table of the Elements has been around for 150 years. Maybe you've felt a certain chemistry with 2019 but don't know why? Maybe it's because this year marks the 150th ...

Every field of science has its favorite anniversary. For physics, it’s Newton’s Principia of 1687, the book that introduced the laws of motion and gravity. Biology celebrates Darwin’s On the Origin of ...
