The two furthest apart in the galvanic series - for all practical purposes this is magnesium and Gold

Metals from which groups might be used to provide a protective coating?
Metals from groups 13-15 could be used. The metals in these mixed groups are not very reactive, and so could provide protection against corrosion.
Where in the reactivity series are the metals most affected by corrosion?
The rate of corrosion is directly linked to a metal's reactivity. The higher the metal in the series, the more reactive, also more susceptible to corrosion with oxygen and water. aluminum is not easy to corrode. Aluminum quickly reacts with oxygen in the air, and the oxide layer that forms protects the metal underneath from any further reaction.
Why can aluminum resist corrosion?
When exposed to air the surface of a piece of aluminum will oxidize and form a coating of aluminum oxide, known in its mineral form as corundum. Aluminum oxide is one of the hardest substances on Earth and so protects the aluminum from further oxidation. It is possible to get aluminum to corrode. Mercury will prevent the oxide from forming a protective coating.
Are all elements metals?
No, not all metals are considered to be elements. Brass for example is a combination of elements but is not an element itself.
What are properties of metal and non-metal?
What are the properties of metals and non-metals? basically :Properties of Metals; *Tensıle strength , *shear strength , *compressıve strength , *ductility,*malleability, *toughness,*corrosion , *electric and thermal conductivity, *brittleness. *Luster * Conductivityand you asked non metals but you have to decide what kind of material what you asked there are 6 main kind of matter like ceramics , composites , carbons , metals&alloys , polymers...=== ===
What combination of metals would electrolytic corrosion be most pronounced.?
if this is for a course with T4TS which i think it is as i searched the same question, its D aluminium and magnesium
When was the process of anodising first used for industrial purposes?
Anodising is a electrolytic passivation process, used on metals to increase corrosion resistance and for better adhesion of paint. It was first used for industrial purposes in 1923, to protect seaplane parts from corrosion.
What are some methods in minimizing corrosion among metals?
Metals are usually treated with a coating that helps minimize the forming of corrosion. Steel is treated to galvanize it from developing rust, which is a type of corrosion. Electroplating is another way to minimize corrosion in metals.
Corrosion is a physical property of metals?
No, corrosion is a chemical change of the metal involved.
Can you call the corrosion of all metals as rusting?
No. Rust (iron oxide) only occurs in metals containing iron. A couple examples of different types of corrosion are galvanic corrosion and chloride pitting corrosion.
Is it ok to connect brass pipe to copper pipe?
Absolutely, positively, YES as both are non ferrous metals and there is no possibility of galvanic corrosion or electrolytic action taking place. Presuming your taking about RED BRASS as opposed to Yellow
What is corrosion of metals?
The corrosion of metals is the gradual destruction by chemical reaction with its environment. This process involves the electrochemical oxidation of metals in reaction with an oxidant such as oxygen.
Is Corrosion is a physical property of metals?
No, corrosion is a chemical change of the metal involved.
What change to a metal is a chemical change?
Corrosion. Oxidation, combination of the surface atoms with oxygen, called rust in the case of iron, is one form of corrosion. Aluminum and many other metals oxidize. Combination with sulfur is also common, particularly for copper compounds. All metals except gold corrode in some fashion.
What metals are most affected and least affected by metal corrosion What causes metal corrosion Hows is metal corrosion caused by water and how is it related to it?
Corrosion is a chemical reaction; corrosion of iron is the reaction with water in the presence of oxygen. Metals as Pt, Au, Ta, Rh, Ru, etc are less sensible to corrosion.
Is corrosion of metals is physical?
corrosion of metals is a chemical reaction between metal and oxygen in atmosphere. Oxidation of metals called corrosion. It affects the physical properties of metal in either way like rusting, colour change, life cycle shortening etc.
When metal enters a chemical reaction what is it called?
The process called when metal is destroyed by a chemical reaction is called Corrosion. Electrochemical of oxidation of metals reacts with oxygen thus corrosion will occur on metals.
