You've probably seen videos showing characters walking through walls like ghosts. Upon closer inspection, atoms consist of a vast majority of empty space. So why is physical reality ...

An introductory course in chemistry suitable for students with little previous experience in the subject. The basic concepts of chemistry, including atoms and molecules, the periodic table, bonding, ...

In this feature, molecules are depicted in two ways. Methane, for example, is written out as CH 4. This shows that the molecule consists of one atom of carbon and four atoms of hydrogen. The molecule ...

Atomic orbitals exist, sort of. The lobes, spheres, and donuts familiar to many chemists are like a map of where you might find electrons around a nucleus. The geometric patterns and motifs that atoms ...

For the first time, scientists have successfully trapped atoms of krypton (Kr), a noble gas, inside a carbon nanotube to form a one-dimensional gas. Scientists from the University of Nottingham’s ...
