I assume you are making some kind of a battery using a galvanized nail, some kind of copper electrode, and some kind of an acid substrate like a lemon.
Every element has a property called Electronegativity which is essentially the force to push an electron from one element to another.
The electronegativity of the following elements are:
Copper: 190
Zinc: 165
Iron: 183
Essentially the bigger the difference between the two, the more power you will get from your battery.
Thus, you are more interested in the zinc coating than the actual iron in your nail. You could have chosen other sources of zinc that would have been equally acceptable. For example you can buy pure zinc sacrificial anodes from most boat supply shops, or if you are careful you can carefully sand the copper off of "modern" pennies to get to the zinc core.
Your battery would probably work with just bare steel/iron for either electrode, but you would get a lot less power. It would be a good experiment. Iron also has a tendency to oxidize/rust which would decrease it's ability to conduct electricity.

Difference between reference electrode and indicator electrode?
Often electrochemical studies are interested in one of the electrodes of the cell only. The second electrode is present to complete the cell. Electrode of interest is named working electrode or the indicator electrode; the second electrode is know as reference electrode or auxiliary electrode (counter electrode).
What is the difference between mono polar and bipolar electrode?
Monopolar electrode is single electrode measure voltage with respect to grond ,but bipolar electrode is two electrode measures the diff. voltage mainly bipolar is used inorder to get high Signal to Noise ratio.
What type of electrodes are used in potentiometric titration?
Potentiometric titration is a method to detect potential difference between the indicator electrode and reference electrode and thus determine concentration of chemical component, which reacts with reagent added to a solution potentially in equilibrium at the beginning.The popularly used reference electrode is either silver-silver chloride or mercury sulfate electrode, and the indicator electrode is generally made of glass electrode, platinum electrode and silver electrode or ion selective electrode.
What is the correct name for covering an electrode?
The correct term for covering an electrode is electrode coating or electrode insulation. This coating is used to protect the electrode from environmental factors and to enhance its performance and longevity.
What is the alternative materials that can be use for magnesium electrode?
Some alternative materials that can be used for magnesium electrodes include graphite, platinum, titanium, and carbon-based materials like carbon nanotubes. These materials can offer different properties and performance characteristics compared to pure magnesium electrodes.
Why is galvanised iron used on roofs rather than untreated iron?
The zinc coating of galvanizing delays the oxidation (rusting) of the iron for a long time.

Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
What other metals can you use for a lemon battery?
In addition to copper, which is commonly used as the positive electrode, you can use metals such as zinc, aluminum, or iron for the negative electrode in a lemon battery. Zinc, often found in galvanized nails, is particularly effective due to its electrochemical properties. Aluminum can also work, but it may corrode quickly in acidic environments. Iron can be used, but it may not generate as much voltage as zinc or copper.

What does 7018 welding rod cost?
E7018 is a shielded metal arc welding (SMAW) electrode. 'E' stands for electrode. '70' stands for 70000 psi minimum as welded tensile strength. '1' designates the position the electrode can be welded in, in this case all positions. '8' classifies that the electrode is a low hydrogen electrode and contains a higher amount of iron powder.
