This traces the evolution of the practice from the Greeks, who figured it was from Egypt, through the Arabs. The efforts of the alchemists, curiously, paid off with the discovery and manipulation of other elements, such as Sulfur, Arsenic, Antimony, Bismuth, and Phosphorus. At right, we ...

The proposal of a Periodic Table could not have happened without an understanding of what is required for a substance to be defined as a chemical element and the discovery of sufficient elements to provide a reasonably large sample to attempt to find an ordered pattern. This chapter traces how...
