Silver Element Facts
Silver and lead often appear together in nature, for example in the mineral galena which is mainly lead sulfide. Galena actually looks metallic (see image) and would have caught the eyes of people looking for metals. The silver objects found in Greece, Turkey and Kish were made of silver that was refined from lead-containing ores such as galena.
GALENA: THE FIRST SEMICONDUCTOR
Galena's chemistry and crystal-lattice structure is the key to its ability to rectify alternating current. The galena lattice consists of a repetitive sequence of lead and sulfur atoms. Theoretically, a pure galena crystal consisting only of lead and sulfur would just function as a weak electrical conductor.
