About Silver

Silver (Ag) possesses the highest electrical and thermal conductivity of any metal, a property that anchors its role in electronics and precision instruments. Element 47 lies in group 11 of period 5 in the d-block, with an atomic mass of 107.87, the electron configuration [Kr] 4d¹⁰ 5s¹, and a Pauling electronegativity of 1.93. Beyond electronics, silver has been worked into jewelry and coinage since antiquity and was central to photographic film through its light-sensitive halide salts. The metal is soft, lustrous, and solid at standard conditions, taking a brilliant polish while remaining more chemically reactive than gold, with which it shares group 11.
