An element is made from just one type of atom , and examples include oxygen, hydrogen and iron. Some elements exist as individual atoms, but some exist as molecules.

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 ...

A chemical element is one of those squares on the periodic table that adorns many a classroom wall. Sure. But what is an element really? It is a more subtle question that you might realise. To get ...

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory are using the 88-Inch Cyclotron to help steady ...

Astronomers at Leiden University have detected rare isotopes of carbon and oxygen in our neighboring stars for the first time ...

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 ...

To produce element 112 atoms, scientists accelerate charged zinc atoms – zinc ions for short – with the help of the 120 m long particle accelerator at GSI and “fire” them onto a lead target.

Surprisingly, no one knows the stars’ exact chemical composition: how many carbon, nitrogen and oxygen atoms they have relative to hydrogen, the most common element.
