Element | Silver |
Symbol | Ag |
Atomic Mass | 107.8682 |
Atomic Number | 47 |
Name Origins | Anglo Saxon, siolfur = silver: Latin, argentum |
Year Discovered | Prehistoric |
Discovered Credits | Known to ancient civilizations. |
Remarks | Soft, malleable metal with characteristic silver sheen. Stable to water and oxygen but attacked by sulfur compounds in air to form black sulfide layer. Dissolves in sulfuric and nitric acid. Used in photography, silverware, jewelry, electrical industry, and glass (mirrors). |
Diagnostic Tests | Easily reduced on charcoal using a blowpipe or propane torch after roasting the sample forming a malleable silvery bead. Silver, along with lead and mercury form white, insoluble chlorides from aqueous solutions. |
