  1. The word silver comes from the Anglo-Saxon word seolfor. There is no word that rhymes with the English word silver.
  2. Silver is exceptionally shiny! It is the most reflective element, which makes it useful in mirrors, telescopes, microscopes and solar cells. Polished silver reflects 95% of the visible light spectrum. However, silver is a poor reflector of ultraviolet light.

  1. Silver has been known since ancient time. It was one of the first five metals to be discovered. Mankind learned to separate silver from lead back in 3000 BC. Silver objects have been found dating back before 4000 BC. It is believed the element was discovered around 5000 BC.
  2. Silver can exist in its native state. In other words, nuggets or crystals of pure silver exist in nature. Silver also occurs as a natural alloy with gold that is called electrum. Silver commonly occurs in copper, lead, and zinc ores.
  3. Silver metal is not toxic to humans. In fact, it can be used as a food decoration. However, most silver salts are toxic. Silver is germicidal, meaning it kills bacteria and other lower organisms.
  4. Silver is the best electric conductor of the elements. It is used as the standard by which other conductors are measured. On a scale of 0 to 100, silver ranks 100 in terms of electrical conductivity. Copper ranks 97 and gold ranks 76.
  5. Only gold is more ductile than silver. An ounce of silver can be drawn into a wire 8,000 feet long.

  1. The most commonly encountered form of silver is sterling silver. Sterling silver consists of 92.5% silver, with the balance consists of other metals, usually copper.

  8. The compound silver iodide has been used for cloud seeding, to cause clouds to produce rain and try to control hurricanes.
  9. The price of silver presently is less than that of gold, varying according to demand, discovery of sources and the invention of methods of separating the metal from other elements. In ancient Egypt and Medieval European countries, silver was valued more highly than gold.
  10. Silver's atomic number is 47, with an atomic weight of 107.8682.
  11. Silver is stable in oxygen and water, but it tarnishes in air because of a reaction with sulfur compounds to form a black sulfide layer.
