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 ...

The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other ...

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 ...

In gases, such as air, atoms and molecules are separated from each other by lots of space. In solids, such as a rock or a ...

Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) are credited in the discovery of 16 of the 118 known elements. Now they’ve completed the crucial first ...
