In the Galvanic Series, which type of metal is more active for corrosion?

In the context of the Galvanic Series, anode metals are more active for corrosion because they tend to oxidize, losing electrons and therefore corroding more readily than other types of metals. The Galvanic Series ranks metals based on their electrochemical potential, with anodes positioned at the more active end. When two different metals are in contact in electrolyte, the more active (anode) metal will corrode at a faster rate to provide electrons, while the less active (cathode) metal will be protected from corrosion.

This principle is critical in understanding galvanic corrosion, which can occur when dissimilar metals are connected in the presence of an electrolyte, promoting the corrosion of the more active metal. As a result, when evaluating choices like cathode metals, neutral metals, and inert metals, these typically do not corrode as actively or are less likely to oxidize compared to anode metals.
