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.
What metal turns green and why?
Copper turns green after a while because of weathering and corrosion. It is in general the Oxygen in our atmosphere that bonds with the copper, forming a protective layer of "green" oxydation or corrosion. Further information: Many buildings have copper-roofs. It is a metal that is easy to cut and form. It is also highly corrosion resistant because the corrosion formed also protects it from further corrosion. Acid rain however is able to wash away part of the corrosion formed. This mean that in highly polluted areas, Copper is not such a good choice. The Statue of Liberty used to be the iconic copper color.

When copper turns green when exposed to the environment a physical or chemical change?
First, copper doesn't "turn green," it reacts with oxygen in the air to form copper oxide. This is a chemical change, because copper oxide is a substance that was not there before.
What element turns white when exposed to air?
Copper (Cu) is the element that turns green when exposed to moist air.
Why the statues of liberty is green?
The Statue of Liberty is made out of a copper element. When copper erodes or is exposed to oxygen progressively, it turns green.

Will the colour of copper turns to green due to overexposure to sodium chloride?
Copper will turn green when it's exposed to sodium chloride or salt.
Do metals other than copper turn green?
No metal actually "turns green", although copper and possibly others develop surface layers that are green when exposed to many natural atmospheres. Copper turns green when it reacts with sulphur (sulfur) in the air, forming copper sulfide.
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...
Does copper turn green?
yes copper turns green when exposed to moist air for a long time as green metal is a mixture of copper hydroxide and copper carbonate 2CU+H2O+O2 --> CU(OH)2+CUCO3
Does silver turn green?

When copper oxidizesit turns?
green
