Is the property of brass totally different from copper and zinc?
No. For example, copper reacts with oxygen to produce a green substance called patina or verdigris. Because brass is an alloy (mixture) of copper and zinc, the copper in brass will over time turn green, but can be cleaned with a polish made for brass.
What is the name of the process that turns a penny green?
That green stuff that shows up on copper is called verdigris, and is also known as patina. In addition to making your penny green, it's also what makes the copper Statue of Liberty look green!The process by which verdigris is made is called oxidation. Most of the time, when copper oxidizes, it turns dark brown, like most pennies you see. When saltwater is added (like in somebody's sweaty pocket) the copper turns green instead.

The Statue of Liberty looks green because copper has a property of turning green due to carbon dioxide and the moisture in the air. That is not rusting; it is called copper patina. More infoExposure to air or oxygen causes the brownish film on copper piping. Water - especially mineralized water - causes greenish or bluish corrosion. And deionized water can pull copper metal from the piping and cause pitting or damage.The term "rusting" is reserved for the corrosion of iron.Copper does not rust. Rust is a mixture of hydrated iron oxides so, by definition, if will only form on iron and iron-rich materials (such as some types of steel). Copper can get a covering of Verdigris, which is a green-colored compound.

What is the word for copper turning green?
The word is "oxidation", which in the case of copper is a three-step process where the copper oxidizes to copper oxide, then to cuprous or cupric sulfide, and then to copper carbonate. Copper carbonate is the green colored copper or patina that forms over time. The old name for this green patina is "verdigris".
What is causing the copper in your attic to turn green?
