Silver is a chemical element; it has symbol Ag (from Latin argentum 'silver', ... accounts for many of the singular properties of metallic silver. ...
Sterling silver is an alloy composed by weight of 92.5% silver and 7.5% other metals, ... a higher grade silver alloy with unique working properties (93.6% or 96%)
Silver and most silver compounds have an oligodynamic effect and are toxic for bacteria, algae, and fungi in vitro. The antibacterial action of silver is dependent on the silver ion. [12] The effectiveness of silver compounds as an antiseptic is based on the ability of the biologically active silver ion (Ag +
Some silver oxide powder.. Silver is a relatively unreactive metal, although it can form several compounds. The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO 3); +2 (highly oxidising; for example, silver(II) fluoride, AgF 2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III ...
Group 11, by modern IUPAC numbering, [1] is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), gold (Au), and roentgenium (Rg), although no chemical experiments have yet been carried out to confirm that roentgenium behaves like the heavier homologue to gold.
The elements to the left of gold and silver have incompletely filled d-bands, which is believed to play a role in their catalytic properties. A common explanation is the d-band filling model of Hammer and Jens Nørskov , [ 18 ] [ 19 ] where the total d-bands are considered, not just the unoccupied states.

Silver nanoparticle depositions in the membrane can impact regulation of solutes, exchange of proteins and cell recognition. [112] Exposure to silver nanoparticles has been associated with "inflammatory, oxidative, genotoxic, and cytotoxic consequences"; the silver particulates primarily accumulate in the liver.
