There really isn't a most stable metal on the galvanic series. The series works with pairs of metals having differences is voltage potentials, very much like a battery made of two metals placed in an acid solution. Dissimilar metals together, such as copper and iron, will create a galvanic cell. On the galvanic chart, metals are arranged according to their galvanic potential voltages, with the ones at the far ends most likely to be unstable. This is manifest in the corrosion of one metal to deposit onto the other metal, similar to a metal plating situation. The closer any two metals are on the series, the more stable they are. The further they are apart, the more likely one is to corrode. This occurs often in waterworks and Plumbing with metallic pipes. Others are invited to check my verbiage on the description.
What else can I help you with?
If steel and copper were in contact in an electrolyte which would corrode?
In this scenario, copper would corrode because it is lower in the galvanic series compared to steel. When two dissimilar metals are in contact in an electrolyte, the metal higher in the galvanic series (steel) acts as the anode and corrodes, while the metal lower in the series (copper) acts as the cathode and is protected.
Difference between electrochemical series and galvanic series?
Electrochemical series-The position of a given metal in electrochemical series is fixed.there is no info. regarding position of alloys.it tells the relative displacement tendencies.Galvanic series-position may shift.alloys are included.predicts relative corrosion tendencies.
Why corroded metal is more stable than pure metal?
Corroded metal is not stable.
How do sacrificial metals protect ship's hulls?
Sacrificial metals work in accordance with the "galvanic series" - the potential for current flow from one metal to another. If you put two metals in an electrolyte, of which seawater is a good one, the less noble or "more anodic" metal will corrode and save the more noble or "more cathodic" metal from corroding. Zinc, being both highly anodic and very cheap to purchase, is the standard sacrificial anode on ships.
Which component, the anode or cathode, is more prone to corrosion in a galvanic cell?
The anode is more prone to corrosion in a galvanic cell.
What corrodes faster than iron?
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. 1. Magnesium 2.

Which is more stable pure metal or its ore?
Pure metal is more stable than its ore because ores are compounds that contain the metal combined with other elements. In order to obtain pure metal from an ore, the ore needs to undergo chemical processes like reduction or electrolysis. This means that pure metal has a higher energy state compared to ores, making it more stable.
Is gold more reactive then copper?
no, gold is the most stable metal that there is.
Will a reaction occur between a metal and a solution of its own metal salt?
No, a reaction will not typically occur between a metal and a solution of its own metal salt. This is because the metal is in a more stable, elemental form and does not have a driving force to displace itself from the salt solution. In general, a metal can only displace another metal from its salt solution if it is higher in the reactivity series.
Why metal aryl is more stable than metal alkyl?
Metal aryl compounds are more stable than metal alkyl compounds due to the greater resonance stabilization provided by the aromatic ring in the aryl group. This resonance delocalizes the charges and stabilizes the molecule. In contrast, metal alkyl compounds lack this resonance stabilization and are therefore comparatively less stable.
Steel is cathode what is anode?
If steel is the cathode in a galvanic cell, then another metal must be the anode. The anode is where oxidation occurs, so a metal that oxidizes more readily than steel, such as zinc or magnesium, would likely be the anode in this scenario.
How does activity series of metals reflect the stability of metals?
The metals highest on the list are the least stable.
