Two electrodes in electrolyte solutions
Electrons flow in the opposite direction.
In a standard galvanic cell using zinc and aluminum, the zinc metal will act as the anode and the aluminum metal will act as the cathode. Zinc will undergo oxidation at the anode, releasing electrons which flow through the external circuit to the cathode where aluminum will undergo reduction. This flow of electrons creates an electrical current.

The stranded cell notation for a galvanic cell made with magnesium (Mg) and gold (Au) is written as: [ \text{Mg(s)} | \text{Mg}^{2+}(aq) || \text{Au}^{3+}(aq) | \text{Au(s)} ] In this notation, the anode (Mg) is on the left side, while the cathode (Au) is on the right, with a double vertical line (||) representing the salt bridge that separates the two half-cells.
the gold electrode
Electrons flow in the opposite direction.
In a galvanic cell with silver and nickel electrodes, nickel is oxidized at the anode. During oxidation, nickel atoms lose electrons and become Ni2+ ions, contributing to the flow of electrons in the cell. Silver acts as the cathode where reduction reactions take place.
the nickel metal
In a standard galvanic cell using zinc and aluminum, the zinc metal will act as the anode and the aluminum metal will act as the cathode. Zinc will undergo oxidation at the anode, releasing electrons which flow through the external circuit to the cathode where aluminum will undergo reduction. This flow of electrons creates an electrical current.
In a galvanic cell with silver and nickel electrodes, the nickel electrode will be oxidized. Oxidation occurs at the anode, where electrons are released as nickel atoms lose electrons and form nickel ions. Silver ions from the other electrode will capture these electrons as the reduction reaction occurs at the cathode.

The voltage of a galvanic cell made with silver and nickel will depend on the specific conditions of the cell, such as the concentrations of the electrolytes and the temperature. Typically, a cell made with silver and nickel could have a voltage range between 0.8 to 1.0 V.

A voltaic battery is also known as a voltaic pile, which is a set (or pile) of galvanic cells linked together in series to create a larger voltage than could be generated by a single galvanic cell. Therefore a voltaic cell would simply be one element of the pile which is also one galvanic cell.
