Art Representing a Beryllium Atom
24" x 18"
Photographic Print

Atomic structure. Computer artwork representing a single atom of beryllium (symbol: Be). This is the traditional way the structure of an atom is depicted, showing electrons orbiting in paths around a central nucleus. Beryllium contains four electrons (blurred in motion), and a nucleus which has four protons and five neutrons (not seen). The number of electrically positive protons balances the number of negatively charged electrons. This image is highly schematic. Scientists now believe that electron orbits are more eccentric and electrons inhabit a cloud of probability rather than moving in well- defined orbital paths (often
