Copper is the metal that forms a green basic carbonate coating, known as patina or copper carbonate, when exposed to the atmosphere. This green layer develops over time as copper reacts with moisture and carbon dioxide in the air, resulting in a protective coating that inhibits further corrosion. The process is often seen on copper roofs, statues, and other outdoor structures.
Copper forms a green rust known as basic copper carbonate or malachite when exposed to oxygen and moisture over time.
The green color coating formed on copper when exposed to air is called patina. Patina is a result of the copper reacting with oxygen and moisture in the air, forming copper oxide and copper carbonate compounds. It is a natural process that eventually protects the underlying copper from further corrosion.
When copper is exposed to moist air for a long time, it acquires a dull green coating. The green material is a mixture of copper hydroxide and copper carbonate. This film called 'verdigris' protects the underlying metal from further damage. 2Cu + H2O+CO2 + O2 Cu(OH)2 + CuCO3
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.
my question is what is green bench? and how it is related to green house effect in atmoshphere?
Copper carbonate hydroxide -Cu2CO3(OH) - is formed on the surface.

Yes; the green basic copper carbonate is formed on the surface.
On the copper surface basic copper carbonate is formed.
During a long time a coating of green hydrated copper carbonate is formed.
if solution is dark green then it is the carbonate of chromium +2 . if it is parrot green then carbonate of nickle +2 and if it is yellowish green then is carbonate of iron +2 or ferrous.
This is a chemical property. The reaction of green carbonate with moist air to form a different substance involves a change in the chemical composition of the substance, indicating a chemical reaction.
Zaratite is a rare mineral that is a hydrated basic nickel carbonate. It typically forms in small green crystalline masses and is often associated with serpentinite rocks. Zaratite is named after the Zarate district in Argentina where it was first discovered.
Universal indicator changes to a color in the green/blue range when carbonate acid is added. This indicates a basic or alkaline pH level.
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
Yes, copper typically forms a greenish patina when exposed to the environment for a period of time. This is due to the oxidation process, which creates copper carbonate on the surface of the metal, giving it a green color.
