Question:

Why would you use Aluminum or Zinc as a Sacrificial Anode instead of Gold, Copper, or Iron?

Aren't Gold, Copper, and Iron less reactive than Aluminum and Zinc? So why not use metals that are the least reactive like gold, copper, or iron as sacrificial anodes instead?

because you want a more reactive metalthe idea is to take the electrons before they get to the important metal
