The black silver sulfide is formed on the surface of metal.
When silver is combined with sulfur, it forms a layer of black silver sulfide. Being exposed to air and sulfur will cause any type of silver to tarnish.
For example halogens and sulfur reacts with silver.
S stands for Sulfur, or Sulphur if you're in England. Ag is Silver.
naturally occurring sulfur oxide causes silver to turn black over time. The concentrated sulfur, about 6% in Spot treatments, just increases the speed of this chemical reaction. Toothpaste with Zinc and silver-cleaner cloth takes care of it.
Sulfur and phosphorus would most like form the compound P2S5
Sulfur causes silver to tarnish.
Sulfur is an element and as such no silver would be found in pure sulfur except as a trace element.
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.
The silver sulfide is Ag2S.

That "tint" on silver coins is called "tone". Do not remove the toning, polish, or clean the coin as it will decrease the coins value. A 100 year old coin should not look as if it was freshly minted yesterday. Toning is the result of sulfides in the air, Sulfur dioxide, temperature, time, and moisture. The most desirable is "rainbow toned" coins. Collector will often pay hundred of dollars more for coins showing varying bands of color.
Ag2S = silver sulfide

Silver is a metal. Sulphur is a nonmetal.

silver and sulfur? Silver is a +1 ion and sulfur is a -2. I think you can balance those charges.
