Structure of the atom. Size of an atom; Atomic number and mass number; How many protons, neutrons and electrons; ... Carbon dioxide, CO₂: each molecule has one carbon atom and two oxygen atoms.

True one-dimensional (1D) crystals with single-atom thickness have been realized only for few elemental metals (Au, Ag) or carbon, all of which showed very short lifetimes under ambient conditions.

Scientists at ETH Zurich have developed a powerful method to look deep inside single-atom catalysts—materials where every ...

The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron ...
