Re: zinc to copper

Copper ions in direct contact with zinc metal are not stable and a spontaneous reaction occurs so electrons are directly flow from the zinc to copper.

Re: zinc to copper

Don't mean to necro, but this only got one post so I thought I'd answer.

Another answer, in addition to the one micle offered, is that zinc has a lower standard reduction potential than copper, meaning it is easier to reduce (give electrons to) copper.
