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 ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a process during which the energy-rich molecule ATP is produced. Cells require ...

But what is it really but a collection of ordinary carbon atoms—the same kind of atom that makes up 18 percent of your body and is an essential ingredient of all living things? This Hot Science ...

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 ...

The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

The number of bonds a carbon atom forms with other elements in a compound determines its chemical structure and behavior. Normally, a carbon atom shares all four of its valence electrons to create ...

Explain that a water molecule has two hydrogen atoms and one oxygen atom. Ask students to use Snap Cubes to make a water molecule. Then show students the animated Snap Cube model of a water molecule.

Researchers from the University of Würzburg are opening up new horizons in chemistry: They present the world's first triple ...
