Corroded metal is not stable.
Not necessarily. The conductivity depends on what metal it is and how pure it is.
Alloys have improved mechanical properties, hardness, resistance to corrosion, resistance to heating, stable crystalline structure etc. compared with pure metals.
cooper is a pure metal
A pure metal is just that; that metal, thus pure metals contain just one metal. For example aluminium foil contains just aluminium atoms. Alloys are one or more metals/elements that make up the metal, e.g C and Fe in steel.
A pure metal is any metal that has not been joined with any other metal or synthetic material.A pure metal is any metal with a very low content of impurities.Something that doesn't exist in real life.A pure metal would be one with absolutely nothing else but that metal in it. You will never see it because metal always has more than one thing in it. Some metals have naturally occurring impurities. Others react with the atmosphere. And still others are a mixture of metals and nonmetals selected for a specific application.
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.
- gold has a very specific and beautiful color, easily to identify - gold is not corroded - gold is a mineral as a pure metal
silver
yes, a 100 percent pure metal can get corroded. corrosion is a surface phenomena. pure metals are likely to get corroded than the metals with some impurity. for example, aluminum in its purest form (say 100 %) gets corroded easily but when aluminum is exposed to air it forms a thin layer of alumina which in turn prevents the inner layers to get corroded (now purity of aluminum has decreased, say 95%). hence corrosion has got its useful side too!

An alloy is better than a metal in pure form in the way that an alloy contains some extra materials possessing some different properties which would prevent it from getting corroded easily and thus increase its life span for using purposes.

pure metal
A pure metal contains only one metal while an alloy is a mixture of two or more metals.
Metals combine with oxygen to form metal oxides in a process called oxidation. This occurs because metals have a tendency to lose electrons, forming positive ions, while oxygen has a high affinity for gaining electrons. The resulting metal oxides are more stable compounds compared to the pure metal.
Getting more out of the metal. Pure economics.
No! A alloy can be a number of different materials plus one or more metal. A pure metal like the element Cu copper does not have any other matter in it besides itself
