Elements heavier than uranium don’t exist naturally on Earth. Researchers make these massive elements at the end of the periodic table by smashing existing atoms together in particle accelerators.

Researchers have directly observed the heaviest atom yet participating in a chemical reaction and forming a molecule. The finding pushes “superheavy” chemistry, which involves extremely massive ...

Recognize these rows and columns? You may remember a detail or two about this mighty table’s organization from a long-ago chemistry class. Elements are ordered according to their number of protons, or ...

It’s all thanks to a titanium beam.

If you wanted to create the world’s next undiscovered element, number 119 in the periodic table, here’s a possible recipe. Take a few milligrams of berkelium, a rare radioactive metal that can be made ...
