What does a negative electron potential mean? So, if an element or compound has a negative standard electrode reduction potential, it means it forms ions easily. The more negative the value, the easier it is for that element or compound to form ions (be oxidised, and be a reducing agent).A negative cell potential (voltage) indicates a non-spontaneous reaction (the opposite reaction will, therefore, be spontaneous!). Redox potential (voltage) is a measure of how easily a metal (or other ion) will give up electrons or retain electrons, not the likelihood for a specific oxidation or reduction reaction occurring.Emma Jones, a spokesperson for the Fed, declined to comment on why many Fed officials, who in the past moved swiftly to acknowledge the war in Ukraine, weren’t addressing the war in Israel.A negative reduction potential, on the other hand, indicates a reaction that would not occur spontaneously.
