Copper, silver, and brass tarnish.
Wiki User
∙ 11y ago
Metals such as silver, brass, copper, and bronze are known to tarnish over time due to exposure to air and moisture. Tarnishing is the result of a chemical reaction that forms a layer of corrosion on the metal surface, giving it a dull or discolored appearance. Regular cleaning and proper storage can help prevent tarnishing of these metals.

What is tarnish relationship?
Tarnish is a phenomenon where metals, like silver or copper, react with substances in the air or on the surface of the metal itself, causing a discoloration or dullness. The relationship between tarnish and metals is chemical in nature, as the metal undergoes oxidation to form the tarnished layer. Preventing tarnish often involves storing metals properly and using protective coatings.
What are two metals that tarnish quickley in air?
Iron and copper are two metals that tarnish quickly in air due to the formation of iron oxide (rust) and copper oxide on their surfaces, respectively.
Does only sterling silver tarnish?
No, sterling silver is a metal alloy that contains 92.5% silver and 7.5% other metals, like copper. Sterling silver can tarnish over time due to exposure to air and moisture. Other metals like brass and copper can also tarnish when exposed to air and moisture.
Does gold tarnish as it ages?
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.
Will an ultrasonic jewelry cleaner remove tarnish?
No, ultrasonic jewelry cleaners are not typically designed to remove tarnish. Tarnish is a chemical reaction that occurs on the surface of metals like silver when exposed to air and moisture. To remove tarnish, you would need to use a specific tarnish-removing product or method tailored for the type of metal you are cleaning.
Do the alkali metals have the ability to tarnish?
By forming their oxides, the alkali metals tarnish very quickly with respect to many other metals.
Why do metals need to be protected against rust and tarnish?
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.

Which groups of elements are silvery-white metals that tarnish when exposed to air?
The elements are the alkali metals.
Is rust the same as tarnish?
Yes, both are forms of oxidation. but rust can penetrate through an entire stell part. tarnish is typically a surface only form of oxidation. Metals like silver are commonly thought to tarnish, but metals such as aluminum also "tarnish", forming an oxide layer almost instantly after fresh metal is exposed.

What are the best metals for making jewelry?
I recommend either sterling silver or silver-plated metals. Others will tarnish and/or break easily.
Does gold tarnish as it ages?
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.
Why do some metals tarnish and some corrode?
Metals tarnish when they react with elements like oxygen or sulfur in the air, forming a thin layer on the surface. Corrosion, on the other hand, occurs when metals react with substances in the environment, such as water or acids, leading to the degradation of the metal over time. The specific chemical properties of each metal determine whether it is more likely to tarnish or corrode.
Will zinc alloy jewelry tarnish?
Yes, zinc alloys e.g brass will tarnish given the "right" conditions.Zinc alloys contain copper, and copper is one of the most tarnish-prone metals there is, so any alloy containing copper will tarnish eventually, depending on the percentage of copper alloyed.
How can you remove tarnish from pageant tiaras?
There is a type of cleaner that you can get at places like Wal-Mart specifically for removing tarnish from metals. I'm not sure what its called but I know of people that have used it for that reason.
