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 ...

Chemical reactions occur when elements or compounds combine and create new compounds. Elements are substances that contain only one type of atom and are represented by unique symbols on the periodic ...

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 ...

The film explains the fundamental concepts of matter, focusing on atoms and molecules. It highlights that everything in the world is made up of atoms, which combine to form molecules. There are over ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. WOMAN: The Greeks had many ideas about the chemistry of things. But the one who came closest to the ...

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 ...

Chemists achieve synthetic feat with radioactive promethium for the first time. “It’s a tour de force,” says Polly Arnold, a chemist at Lawrence Berkeley National Laboratory in Berkeley, California, ...

Changing the chemistry of a compound is difficult by itself, but modifying materials only a few atoms thick is its own challenge. A group of University of Chicago scientists announced an innovative ...

One of the rarest and most mysterious elements in the periodic table has finally given up some crucial chemical secrets, eight decades after its discovery. Researchers at Oak Ridge National Laboratory ...

Helium, the most noble of the noble gases, long thought to be completely inert and thus too standoffish to bond with other atoms, recently surprised chemists by forming chemical compounds after all.
