Okay, I’ve got elements 29 and 30. Which side do I put each on? See the problem? :)

  No, it really doesn't matter. Have you never made a lemon or potato battery before?

    The electrons are flowing towards the element 29 side. Is that left or right?

      Now arrange the apparatus such that the element 29 side is near you, and the element 30 side is far from you. Additionally, ensure that the wire is up (further from the locally dominant gravitational mass). Now place an election between the "lemon" and the wire. See which way the election moved? That was right (or left, I don't remember).

        The electron doesn't move. Edit: if you make the electron move, it will move towards or away from the wire, depending whether it's moving in the same or opposite direction as the electrons in the wire.
