iron will rust faster because the hydrogen molecules combine with metalic molecules in the iron faster which causes the chemical reaction process to speed up sincerly, Jake from AZ 7th grade student
Copper does not rust, but it can develop a patina or greenish tarnish when exposed to air and moisture over time. This patina can actually help protect the copper from further corrosion.
Copper does not rust; it develops a greenish film called patina when exposed to air and moisture. The formation of patina can take several years, depending on the environmental conditions.
Pennies do not rust because they are made of copper-plated zinc. However, the copper plating can react with certain acids and chemicals, causing them to tarnish or develop a patina over time. This is different from rust, which is the result of iron or steel reacting with oxygen and water.
Copper IUDs cannot rust because they are made of copper, which does not rust. However, they may develop a greenish patina over time due to oxidation, which is normal and does not affect the effectiveness of the IUD.

If i remember rightly, rust is just a metal oxide. So on a coin it would be copper reacting with the air, albeit slowly, forming copper oxide.
Plastic pipe does not rust, brass does not rust, copper does not rust. Stainless steel does not rust, lead pipe does not rust.
The only chemical that could make something rust is iron; "rust" refers specifically to the corrosion of iron, so copper cannot rust. However, its corrosion is caused by copper itself being oxidised and forming compounds which are water soluble and also easier to damage.
Most likely some other object has dripped rust onto the copper, which can be removed. Copper does not rust, but it does form a green patina over time.
Oxygen turns copper green.

copper turns to blue-green copper oxide.
