Answer 1

◆Negative electrode potential means the metal electrode is donating electron(s) to another electrode. In other words it is under oxidation process and is reducing the other electrode.

For example… zinc has negative electrode potential value (-0.76 V). So zinc is a reducing electrode. It works as anode (negative) in electrochemical cell. While other electrode which is accepting electron(s) will act as cathode in electrochemical cell.
