Tarnishing involves oxidation on metal. Some examples include rust on pipes and coins, and corrosion on items made of silver.
Tarnish on metal, particularly on silver, is primarily composed of silver sulfide (Ag₂S), which forms when silver reacts with sulfur compounds in the air or from other sources. This reaction leads to a darkening of the metal's surface. Other metals, like copper, can tarnish to form copper oxide or copper carbonate, depending on environmental conditions. Overall, tarnish results from the oxidation and sulfide formation on the metal's surface.
Metals need protection against rust and tarnish because these processes can weaken the metal, leading to degradation and structural integrity issues. Rust is a form of corrosion that occurs when iron reacts with oxygen and water, while tarnish is a result of metal reacting with sulfur compounds in the air. Both can compromise the appearance and functionality of the metal.

When any type of metal is affected by heat, moisture, or gases, the metal begins to tarnish. This is a chemical reaction to whatever substance the metal has come in contact with and is able to react with it.
No, gold does not tarnish as it ages. Gold is a non-reactive metal, so it does not corrode or tarnish like other metals. However, its appearance can change with time due to scratches or other forms of wear.
Pennies and the Statue of Liberty are both made of copper but the Statue of Liberty is now green just like pennies become, although they are shiny when they're new. So copper is the metal that has green tarnish.
Tarnish on a metal could be caused by the formation of compounds such as oxides, sulfides, or chlorides. For example, silver tarnish is often silver sulfide (Ag2S), while copper tarnish is a mixture of copper oxides and sulfides. These compounds form on the surface of the metal in the presence of air and other chemicals.
Silver is a silver-white metal that does not tarnish easily due to its resistance to corrosion.
Yes.
Gold and platinum will not tarnish on a ring.

Palisil metal does not tarnish, as it is a type of stainless steel that is resistant to corrosion and oxidation. This makes it a durable and long-lasting material for various applications.

"Tarnish" can be either a verb or a noun. The noun refers to the product of the action of the same word used as a verb. Example as a verb: "Both silver plate and sterling silver tarnish." Example as a noun: "That old silver medal was so covered with tarnish that at first I thought it was black iron."
