Silver’s physical and chemical properties are intermediate between those of copper and gold. It is a non-metallic element occurring extensively in the earth's crust in silica and silicates, having both an amorphous and a crystalline allotrope. Silver, chemical element of atomic number 47, a white lustrous metal valued for its decorative beauty and electrical conductivity. Electrochemical properties. (Modern antibiotics are now used instead.) It is not a chemically active metal, but it is attacked by nitric acid (forming the nitrate) and by hot concentrated sulfuric acid. Gold’s unique physical properties. In the early 21st century, digital cameras supplanted those that used film, but demand for silver from other sectors—such as for sterling and plated silverware, ornaments, jewelry, coinage, electronic components, and photovoltaic cells—continued to be important. Biological properties. Together with gold and the platinum-group metals, silver is one of the so-called precious metals. Due to this, silver is used for the contact points in all printed circuit boards and is also used in electrical conductors as a coating. Your email address will not be published. Silver for centuries has been used traditionally for coinage by many countries of the world. Silver (Ag), chemical element, a white lustrous metal valued for its decorative beauty and electrical conductivity. Silver has an electrical and thermal conductance that is higher than any other metal. However, due to the unique optical properties of silver nanoparticles, a great deal of information about the physical state of the nanoparticles can be obtained by analyzing the spectral properties of silver nanoparticles in solution.
