If you've ever seen a d4 or a caltrop, you've seen the shape of the bond sites on a carbon atom: four equilateral triangles, arranged into a three-faced pyramid with a triangular base. Every ...

The carbon atom and hydrogen atoms are close together. The electrons from each atom feels the attraction from the proton in the nucleus of the other atom. This attraction pulls the atoms together and ...

A new reagent has moved carbon-atom transfer out of the chemical flatlands, allowing chemists to place a single carbon atom so that it makes bonds to four different substituents. The reagent makes ...

Boron, carbon, nitrogen and oxygen: these four elements can form chemical triple bonds with each other due to their similar ...

Graphyne is a crystalline form of carbon that is distinct from both diamond and graphite. Unlike diamond, where each atom ...

Where diamond has a regular crystal structure, graphene (or at least the Platonic ideal of graphene) is a flat, single-atom-thick sheet of six-sided carbon rings. The hexagonal rings of six carbon ...
