Copper can naturally be found in Lake Michigan and other places all over the world while Zinc can be found in Germany, where many say it had originated. A German scientist was the one to name Zinc.
Yes, it is.
natural, but can me made synthetically by nuclear fusion of hydrogen isotopes.

the answer is that it occurs as a compound, not an element
