WebElectrons are flowing from the zinc solid metal strip to the copper strip. Zinc ions in the solution are positive, and hence the solution on the left side becomes more positive. As it becomes more and more positive electrons can no longer travel to the copper because they are attracted to this strong positive charge. What would happen then? WebOnly the valence electrons in a conductor metal atom usually are involved in the flow of current(1 to 3 out of the many electrons a metal atom has. Copper has 29). These valence electrons too are loosely bound to the nucleus and can be used for current flow easily, this is because on losing a certain amount of electrons these metal atoms ...
