Group 11 element Parkes process. These metals, especially silver, have unusual properties that make them essential for industrial applications outside of their monetary or decorative value. They are all excellent conductors of electricity. The most conductive of all metals are silver, copper and gold in that order. Silver is also the most thermally conductive element, and the most light reflecting element. Silver also has the unusual property that the tarnish that forms on silver is still highly electrically conductive. Copper is used extensively in electrical wiring and circuitry. Gold contacts are sometimes found in precision equipment for their ability to remain corrosion-free. Silver
Etymology of electricity electrical phenomena as kinds of electricity. These multiple definitions are probably the reason that Quantity of Electricity has fallen into disfavor among scientists. Physics textbooks no longer define Quantity of Electricity or Flow of Electricity. Quantity of electricity is now regarded as an archaic usage, and it has slowly been replaced by the terms charge of electricity, then quantity of electric charge, and today simply charge. Since the term "electricity" has increasingly become corrupted by contradictions and unscientific definitions, today's experts instead use the term "charge" to remove any possible confusion. Despite their similarities, substituting the word "charge" for "electricity"
