It is a metallic element with atomic symbol Ag, atomic number 47, and atomic weight 107.8682.
Silver is a naturally occurring element.
It is found in the environment combined with other elements such as sulfide, chloride, and nitrate. Pure silver is “silver” colored, but silver nitrate and silver chloride are powdery white and silver sulfide and silver oxide are dark-gray to black.
Silver is often found as a by-product during the retrieval of copper, lead, zinc, and gold ores.
Silver is used to make jewelry, silverware, electronic equipment, and dental fillings. It is also used to make photographs, in brazing alloys and solders, to disinfect drinking water and water in swimming pools, and as an antibacterial agent. Silver has also been used in lozenges and chewing gum to help people stop smoking.
