Copper turns green because of sulfur pollution in the air, forming copper sulfide.
oxygen.
A penny can turn green when exposed to acidic liquids like lemon juice or vinegar, which cause a chemical reaction with the copper in the penny to create a greenish patina. Saltwater can also cause a copper penny to turn green over time due to oxidation.
A green penny can turn green when exposed to the elements, like oxygen and moisture, causing a chemical reaction with the copper in the penny. This reaction forms copper oxide, which is the green coating that gives the penny its green color.
The pennies turn green because they are open to the air, because they contain copper, and because copper turns green when oxidized.
the Statue of Liberty is green because it has been there for a long time. Since metal rusts, the Statue of Liberty also rusted. In fact, it rusted enough for it to turn green. If a penny rusts enough, it will also turn green.
it would turn a dark color green
A penny can turn green due to the oxidation process when exposed to air and moisture. The speed of this process can vary depending on the conditions it is exposed to, such as humidity level and presence of other chemicals. In general, it can take several weeks to several months for a penny to turn green.
A penny turns green in water due to a chemical reaction between the copper in the penny and the oxygen in the water. This reaction forms a layer of copper oxide on the surface of the penny, giving it a greenish tint.
Acid in the rain reacted with the copper to turn it green. That is why there is sometimes green on pennies. Acid in the rain reacted with the copper to turn it green.

leave it water for about a week or longer, how long it takes depends on size, i would personally start with a penny.
You can also turn pennies and some other coins green by letting them sit overnight in a paper towel soaked in vinegar. and if you want to clan pennies to shine, put them in a cup of vinegar and salt dissolved. (I once tried cleaning them with a pinch of kosher salt instead and it dug a hole through the penny! -NOT RECOMENDED!!!)
The copper metal oxidizes from exposure to air and moisture, forming a coating of copper carbonate.It an also help crops
