There are three general processes by which ions move in solution: diffusion, convection and electrostatic migration.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).
