Silver sulfide is an ionic compound, and is not a metal.
Yes, silver is a metal.
Ag2SMainly Silver(I) Sulfide = Ag2S
The molecular formula for Silver sulfide is Ag2S
Ag2S
Black (Silver Oxide, Ag2O, Only with pure Oxygen)
Zinc sulfide is a covalent compound.
Silver sulfide is an ionic compound, and is not a metal.
Silver sulfide is composed of silver, a metal, and sulfur, a non-metal; therefore, it is an ionic compound and a salt.
The black tarnish on silver is silver sulfide, Ag2S. Presumably you are boiling silver in a metal pot. The salt water completes an electrochemical cell between the silver sulfide and the aluminum, copper, or iron pot. The oxidized silver in silver sulfide is reduced to silver metal, and part of the metal pot is oxidized; the reaction happens because silver wants to be reduced more than the other metals do. You might imagine that as the metal is oxidized it would become iron, copper, or aluminum sulfide, but the metal sulfides, especially aluminum sulfide, are not so stable. Aluminum sulfide hydrolyzes to aluminum hydroxides and hydrogen sulfide, H2S, the stinky gas, which is probably what you are calling "sulfur".
The black silver sulfide is formed on the surface of metal.
Ionic, since it has silver (metal) and Sulfur (nonmetal).
it is a chemical change
The combination of silver and sulfur is silver sulfide (Ag2S). This is a compound with a metal (silver) and a non-metal (sulfur), so we use the metal's name with the non-metal's name changed to end in -ide.
Ag2S is its own compound: silver sulfide.If you mean what elements are in Ag2S, they are silver, and sulfur.
Silver sulfide is formed on the surface of the metal.
The formula of silver sulfide is Ag2S.
Sulfide is not a metal, it is composed from the element sulfur, which is a non metal.
Silver sulfide, Ag2S is a chemical compound.
