The list begins with the more active (anodic) metal and proceeds down the to the least active (cathodic) metal of the galvanic series. A "galvanic series" applies to a particular electrolyte solution, hence for each specific solution which is expected to be encountered for actual use, a different order or series will ensue. In a galvanic couple, the metal higher in the series (or the smaller) represents the anode, and will corrode preferentially in the environment.

Why does magnesium corrodes faster than iron?
Believe it or not, aluminum is technically more reactive than iron. However, when aluminum is exposed to air, it almost instantly forms a microscopic layer of aluminum oxide (Al2O3) which protects the rest of the aluminum from any further reaction. Iron doesn't do this, and therefore corrodes unevenly, making it unsuitable for certain applications.
How does cast iron react to salt water?
It corrodes badly.
What is the most common magnetic element that corrodes to form rust?
The most common magnetic element that corrodes to form rust is iron. When aligned, atoms of iron will possess a magnetic field that will lead to interaction with other magnetic, ferrous materials. Iron will oxidize to form rust.
What was the metal that replaced bronze in the making of weapons and tools?
Iron replaced bronze in the making of weapons and tools. Iron weapons were stronger and more durable than bronze, leading to the Iron Age. This shift occurred around 1200 BCE.
Why does using powdered iron make a reaction go faster than using a single piece of iron?
It has a greater surface area than the single piece of iron
Does copper or iron corrode faster and why?
Iron corrodes faster than copper because iron is more susceptible to oxidation in the presence of moisture and oxygen, leading to the formation of rust. Copper, on the other hand, forms a protective layer of copper oxide (patina) on its surface that slows down the rate of corrosion.
Which would corrode first copper or iron?
Aluminum (US spelling) is actually much more reactive than iron, and would corrode faster. In fact, it corrodes so fast that in forms a coating of aluminum oxide on any surface in contact with air. But since the surface is covered, it protects the rest of the metal, and it never corrodes deeper than a fraction of a millimeter. So technically, aluminum corrodes much faster, but much less completely because most of the mass of it is protected by the corroded layer.
Why does magnesium corrodes faster than iron?

how quickly does an iron nail rust in saltwater?
The combination of moisture, oxygen and salt, especially sodium chloride, damages metal worse than rust does. This combination corrodes, or eats away at, the metal, weakening it and causing it to fall apart. Saltwater corrodes metal five times faster than fresh water does and the salty, humid ocean air causes metal to corrode 10 times faster than air with normal humidity. Bacteria in ocean water also consumes iron and their excretions turn to rust.
What corrodes a penny faster?
acid and coke
Why are many things that are made of iron disposable?
because iron corrodes and its cheap
When Iron corrodes in the presence of air and water to form what?
IRON OXIDE.......AKA RUST!
How does cast iron react to salt water?
It corrodes badly.
What metal corrodes easily to form rusty oxide?
This metal is iron.
What type of water corrodes water faster?
I do not think that water can corrode, can it?
Why wire mesh corrodes faster at joints?
Mesh
