To discharge an ion at the electrode, tye ion involved needs to be electronegative.
In this case, the electronegative ions are spontaneously discharged, while the electropositive ions require electricity before they are discharged.
Hence, the most electropositive 2.0 * Q ^3+
= 6+ electropositivity
Requires the highest electricity to be discharged
