Combining it with other metals or other elements give the usually soft copper a durability that allows it to be used for a number of purposes. Its reddish-brown color makes it easily recognizable, but this metal is used for far more than just the US penny. This verdigris is not like the rust that forms on iron or other metals, but actually layers, covers, and even protects the copper beneath it. This native copper was first used (c. 8000 bce) as a substitute for stone by Neolithic (New Stone Age) humans. The misconception is that copper reacts to the water, when really it’s the oxygen in the water that it reacts to. Copper chemical properties define its chemical formula, isotopes, oxides, electronegativity It dissolves in most adds and in alkalis.
