Silver has no essential biological role. Ag⁺ ions and some silver materials have antimicrobial activity, but excessive exposure can cause argyria, a permanent gray-blue discoloration of skin and tissues.
- Silver is the best electrical conductor among the elements.
- The symbol Ag comes from argentum, the Latin name for silver.
- Silver bromide and related silver halides made film photography possible.
- Silver ions are antimicrobial, which explains many medical and water-treatment uses.
- Silver has atomic number 47 and belongs to group 11.
- Its electron configuration is [Kr] 4d¹⁰ 5s¹.
- Silver commonly forms Ag⁺ compounds.
- Ag⁺ forms characteristic precipitates with halide ions, such as AgCl, AgBr and AgI.
