Why less originated area act as anode in a metal ?

AI Thread Summary
In electrochemical corrosion, areas of a metal that are less exposed to oxygen act as anodes, while regions with higher oxygen concentration function as cathodes. This phenomenon occurs when metals are exposed to moisture and air, leading to corrosion processes. The term "originated area" was initially unclear but was clarified to refer to oxygenated areas, emphasizing the role of oxygen concentration in determining anodic and cathodic behavior in corrosion.

Why less originated area act as anode in a metal ?
 
Chemistry news on Phys.org
What do you mean by "originated area"?
 
Sorry it's oxygenated
 
I am still not sure what the question is really about. In what context was it asked?
 
A metal undergoes a electrochemical corrosion when exposed to moisture air. The parts which are less exposed to oxygen will act as anode and the more oxygen concentrated area will act as cathode
