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 ...

What's the difference between a compound and a mixture? What is the difference between a compound and a mixture? Understand the differences and why mixtures are important.

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 practical method has been devised to synthesize compounds that have previously been almost impossible to make. The combination of fluorine atoms and amide groups in the compounds might be useful in ...

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.
