 * Discovery:** Cadmium was discovered by Friedrich Stromeyer in 1817 from an impurity in some samples pf zinc carbonate, ZnCO3.
 * Name:** Because the metal was associated with Zinc, Friedrich Stromeyer called it Cadmium. meaning cadmium fornacum or furnace calamine. //Calamine// (ZnCO3) was an earth found in Kadmeia in Ancient Greece.
