What are different types of metals in a voltaic cell that have different attractions for electrons?
A Voltaic cell is a spontaneous redox reaction. It has a anode (where oxidation or loss of electrons occurs) and a cathode (where reduction or gain of electrons occurs). There is also a salt bridge to replenish ions and a flow of electrons through an external source. most commonly Zn (Zinc) and Cu (Copper) are used in the reaction.
