Answer:
[tex]M+e^-\rightarrow M^+[/tex]
Explanation:
Hello!
In this case, since corrosion is a reaction by which a metal is oxidized to a form in which it has a higher oxidation state due to the fact that it loses electrons and therefore it becomes positively charged. In such a way, for a general metal M, we could have the following corrosion reaction:
[tex]M+e^-\rightarrow M^+[/tex]
The amount of electrons and the resulting oxidation state depend upon the nature of the metal, for instance, we can see it for silver, zinc and aluminum:
[tex]Ag+e^-\rightarrow Ag^+\\\\Zn+2e^-\rightarrow Zn^{2+}\\\\Al+3e^-\rightarrow Al^{3+}[/tex]
Best regards!
