Consider a galvanic (voltaic) cell that has the generic metals X and Y as electrodes. If X is more reactive than Y (that is, X more readily reacts to form a cation than Y does), classify the following descriptions by whether they apply to the X or Y electrode.
Because X is more reactive than Y, So X is oxidized to X²⁺ and Y²⁺ is reduced to Y. Therefore the overall cell reaction is:
X(s) + Y²⁺(aq) → X²⁺(aq) + Y(s)
X electrode: Electrons in the wire flow away from, Anions from the salt bridge flow toward, Anode, Loses mass
Y electrode: Electrons in the wire flow toward, Cations from the salt bridge flow toward, Cathode, Gains mass

Electrons flow from anode to cathode in a voltaic cell.
A voltaic cell is one in which electrical energy is produced by a redox reaction. Electrons flow from anode to cathode in a voltaic cell and the cell reaction is spontaneous.
Given a generic voltaic cell in which metal X is more reactive than metal Y, it follows that;
