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 term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore ...

The universe is flooded with billions of chemicals, each a tiny pinprick of potential. And we’ve only identified 1% of them. Scientists believe undiscovered chemical compounds could help remove ...

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 ...

A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. The ratio of each element is ...

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.
