I made a simple battery.As electrodes I used a copper plate and a zinc plate and as electrolyte I used tap water.
What happens with the electrodes and the electrolyte after a while?
And why does it work?

Leave it running for a while, an compare the changes, you'll see significant differences, between a new battery, and a dead one.

Thank you for your answers.

After the Zn lost electrons and Cu gained , can they gain/lose electrons in other processes like electrostatic induction to become as they were before the oxidation/reduction reaction?Or they become useless.

So, you want to reverse the reaction, and want to know how?  What do we call a battery that has "run to completetion"?  And how do we "get it back to new"?  And what do we call that -- re--------?  And how's that done?

I know how rechargeable batteries work.

I'm trying to understand how and why different combinations of chemical elements can give away electrons creating a flow of electricity and what happens to those elements after that.How those ionized element behave in other reactions or circumstances.

In my experimental battery , from what I know , Copper has 1 electron in it's last energy layer , Zinc has 2 , Hydrogen has 1 and Oxygen 6. I also don't understand how electrons are transferred from Zn to Cu  through a water molecule.An what happens to that water molecule in this process.

I also would like to know how the number of electrons can influence  the exchange of them between two different chemical elements.

I didn't went to a collage of chemistry so for me this is "uncharted
territory".I need this information for a project of mine regarding energy production.

I appreciate your time replying to my previous questions I hope you can share some of your knowledge or give me some guidance.Thanks!

Great

Well, try to look at it this way.  If you droppped a bar of zinc, into a solution of copper ions, what would happen?  Can you describe that, as a balanced chemical reaction, and also as a pair of half reactions?

That, I'm not sure of.  But I don't think it has significance to the original question, as posted.

I'm not sure where you're going with that, but your half reactions should include the electrons, as a hint for you to figure it out.

I didnt realize that, as you first posted.  See, making a battery is a very common first experiment for beginning chemistry students, so I guessed you were trying to work out school problems.  Try the above links, and see if you can learn enough background to help you understand the whole process.
