Silver - Facts, Symbol, Properties, Uses, Production ...
Properties of silver. Chemically, silver metal is a quite unreactive element with a good conductor of electricity. In learning chemistry, it dissolved in water to the extent of 0.07 mg liter-1 in presence of dissolved oxygen.It is attacked by atmospheric sulfur compounds, mainly hydrogen sulfide (H 2 S). Some properties of the element are maintained below the table.

nickel silver | Facts, Definition, & Uses | Britannica
A natural alloy known as paktong (white copper), smelted by the Chinese from copper-nickel ores, was one of the first alloys used by humans. It was later improved by the addition of zinc ores and was imported into Europe by the East India Company.Not until the 1840s was the alloy made in Europe by mixing the three metals, and it was known as German silver until 1914.
