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 ...

The team made two atoms of element 116, livermorium, during 22 days of operations at the lab's heavy-ion accelerator, the 88-Inch Cyclotron. Making an atom of element 120 would be even rarer, but ...

A research team has discovered clusters of aluminum atoms that have chemical properties similar to single atoms of metallic and nonmetallic elements when they react with iodine. The discovery opens ...

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 ...

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 ...

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 ...

The rare radioactive substance made its way from the United States to Russia on a commercial flight in June 2009. Customs officers balked at accepting the package, which was ensconced in lead ...

A team of Russian and American scientists has discovered a new element that has long stood as a missing link among the heaviest bits of atomic matter ever produced. The element, still nameless, ...
