The green material on copper is oxidation. On iron or steel it is called rust, on copper and bronze is it called a patina. Unlike the rust on steel and iron that damages the metal, rust on copper, bronze, and even aluminum can protect the under-laying metal.
You can even make the green different shades by applying different oxidizers, which some artists use in place of painting the metal.

Why does wearing a copper bracelet turn your skin green?
The green color on your skin after wearing a copper bracelet is a result of a chemical reaction between the copper and your skin's acids and oils, producing copper salts which oxidize and leave a green residue on your skin. This reaction is harmless and can easily be washed off with soap and water.
Will iron oxide turn copper green?
No, iron oxide will not turn copper green. The green patina on copper is typically the result of oxidation due to exposure to air and moisture, which forms copper carbonate or copper chloride compounds. Iron oxide itself does not have this effect on copper.
Is copper turning green in the air physical change?
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
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".
Why does green copper carbonate go black?
Because it undergoes thermal decomposition. If you give heat to Copper (II) carbonate, it will decompose to form Copper (II) oxide. Instead of saying green copper carbonate, I guess it is safer and better to say copper (II) carbonate.
What makes copper go green and how long does it take to change color?
