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 "elēkrŏn", meaning 'shining light'. The letter Q was used for electric charge instead of the letter E because the letter was already used to represent the electron. The word "electric" was first used by Francis Bacon to describe materials like amber that attracted other objects. The first usage of the English word "electricity" is ascribed to Sir Thomas Browne in his 1646 work, "Pseudodoxia Epidemica": In this context, an "Electrick" or "Electrick body" was a non-conductor, or an object capable of attracting "light bodies" (like bits of paper) when excited by friction; a piece of amber is "an Electrick", while
