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 arises because the population of physicists abandoned the term "electricity" without much public discussion and perhaps without much awareness on the part of their community. By silently altering the meaning of common and heavily used terms, the scientific community caused an immense confusion on the part of the public. Whereas in the past the question "What is electricity?" was more or less easily answered, today the question itself has become meaningless. Is electricity a form of energy? Is electricity the same as electric charge? Is electricity nothing but a class of phenomena? Should we measure the quantity of electricity in
