Oxygen turns copper green.
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
by me
Any metal that is an element, like copper, iron, manganese, etc will rust (or oxidize, if you want to get technical).
Rust is a COMPOUND. rust is a element you stupid fool suk my prik
Copper doesn't rust
Copper corrodes, things made of iron rust. Copper can corrode, but it takes longer than it does for iron to rust.
Rust occurs on iron and steel when they oxidize in the presence of moisture and oxygen. Copper does not rust; instead, it forms a patina when it oxidizes, which is a greenish layer that protects the copper from further corrosion.
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.
Plastic pipe does not rust, brass does not rust, copper does not rust. Stainless steel does not rust, lead pipe does not rust.
Copper is an element
Yes, copper is an element.
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.
