Making some researches to answer my last post, I found this article.
It explains that when a piece of zinc and a piece of copper are connected with a conductor, since copper is more elctronegative than zinc, electrons start to flow form zinc to copper till too many electrons has reached the piece of copper and they start to repel the others. Is this explanation accurate?
Can you generalize this observation for other elements connected through a conductor?
Does it work for solid and liquids?

I'm not stating that there will be an electricity flow, I'm asking if there is an amount of electrons that will converge from the zinc to the copper. Even if it happens for a millisecond.

    $\begingroup$ Well, your elements should be conductive to begin with, otherwise they'll have no idea they are connected with a wire. Then again, you can simply rub them against each other. Triboelectric effect is a pretty broad thing, it is not limited to elements. $\endgroup$ – Ivan Neretin Dec 5 '17 at 20:55

  • $\begingroup$ Also I'm quite disappointed with quality of the blog, on scientificamerican domain no less, which you linked it's self contradictory and you pulled one of worst things from it. $\endgroup$ – Mithoron Dec 5 '17 at 22:19

    $\begingroup$ @Mithoron I have to agree with Gabriele. Without a chemical background, its tough to know whether or not a resource like this is trust worthy and it seems harsh to down vote for being confused by what I imagine many outside chemistry would consider a reasonable source. $\endgroup$ – Tyberius Dec 6 '17 at 15:37
