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 ...

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.

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.

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

Carbon is made up of just one type of atom close atomThe smallest particle of an element. We often think of atoms as tiny spheres, but in fact they are made from smaller particles called protons ...

Boron, carbon, nitrogen and oxygen: these four elements can form chemical triple bonds with each other due to their similar electronic properties. Examples of this are the gas carbon monoxide ...

In these drawings, every line is a bond and every bend is a carbon atom. Most hydrogen atoms are not shown, and it is assumed each carbon has enough hydrogens so that each carbon has four bonds.
