Undoubtedly An important oxidation condition for silver in complexes is +1. The Ag+ cation is diamagnetic, like its homologues Cu+ and Au+, as all three have shut-shell electron configurations without unpaired electrons: its complexes are colourless delivered the ligands aren't much too simply polarised for instance I−. Ag+ kinds salts with most anions, however it is hesitant to coordinate to oxygen and thus A large number of salts are insoluble in water: the exceptions tend to be the nitrate, perchlorate, and fluoride. The tetracoordinate tetrahedral aqueous ion [Ag(H2O)4]+ is thought, even so the characteristic geometry for the Ag+ cation is 2-coordinate linear.

To avoid the development of such compounds, ammonia and acetylene needs to be saved away from silver products. Salts of silver with strongly oxidising acids for instance silver chlorate and silver nitrate can explode on connection with materials which might be readily oxidised, for instance natural and organic compounds, sulfur and soot.[132]
