The chemical identity of individual atoms on a surface can now be determined using an incredibly powerful atomic force microscope. It means that scientists can now look at a mixed material and pick ...

Last summer, when more than 8 million trillion calcium ions blasted a thin film of americium atoms nonstop for more than a month, the collisions generated four atoms of never-before-seen element 115, ...

An international team of scientists in Germany has succeeded in the observation of the chemical element 114, one of the heaviest elements created until now. The production of element 114 is very ...

The heaviest element that humans have ever found is called oganesson. Each atom of the stuff packs a whopping 118 protons into its dense center. In contrast, hydrogen—the most abundant element in the ...

As though it wasn’t hard enough to memorize the names and atomic weights of 117 elements in the periodic table, scientists have now confirmed a new one. Researchers from Lund University in Sweden ...

Russian physicists have for the first time created atoms of the super-heavy element 117, filling a gap in the periodic table and providing further evidence that research is close to reaching a ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...
