Silver is a chemical element with symbol Ag and atomic number 47,the silver has long been valued as a precious metal it is also  used in coins ,solar panels, water filtration, jewelry and ornaments , the Silver is used industrially in electrical contacts and conductors, in specialized mirrors, window coatings and in catalysis of chemical reactions. Its compounds are used in photographic film and X-rays. Silver is produced during certain types of supernova explosions by nucleosynthesis from lighter elements through the r-process, a form of nuclear fusion that produces many elements heavier than iron, of which silver is one
Among metals, silver has the highest thermal conductivity
