because when corrosion occours on a metal the chemical reaction is an oxidation. This means that the metal will loose electrons and became a positive ion.
Fe ------> Fe 2+ + 2 e-
The iron is oxydised from metal to metal ion.

∙ 12y agoRust is an oxidation reaction because the Iron ion (Fe+2) is combining with an Oxygen ion (O-2) in a chemical bond. Some periodic tables have oxidation numbers (even more than one for some elements) in the upper right hand corner of each element's box.
In addition to rust, many ions form common compounds that we use everyday (NaCl is a positive sodium ion combined with a negative chlorine ion).
Simply put, to form ionic bonds, usually two elements will stabilize each other by one element lending a certain number of electrons to the other.

Iron goes into solution as Fe++ ions. As these ions go into solution, the metal becomes negatively charged (by the electrons left behind) with respect to the electrolyte.

What type of reaction is occurring when a metal undergoes corrosion?
Oxidation reduction
What is metal corrosion?
Metal Corrosion or Metallic Corrosion can be defined as the destructive attack of a metal through interaction with its environment.The most common example is Rust, an iron oxide Fe2O3, that is the consequence of the Corrosion process of Iron.
Why is fire considered an example of oxidation?
Because oxygen supports combustion.
The reaction of a metal with oxygen to form rust is called?
Metal Oxide is the general term for reaction with oxygen. Rust is usually a specific referral to Iron Oxide Fe2O3. This process is called oxidation.
The oxidation state of CoCO3?
Co = +2 oxidation C = +4 oxidation O = -2 oxidation
What is difference between corrosion resistance and oxidation resistance?
corrosion resistance is resistant against chemicals oxidation resisstance is restant against oxigen
What kind of metal is affected by corrosion?
Most metals suffer corrosion. There are few (gold, platinum) that do not. Metals that create a hardy oxidation layer, one that is insoluble in water, are considered "stainless" or can be "passivated".
Why are rusting and tarnishing examples of corrosion?
Rusting and tarnishing are examples of slow oxidation, where the naturally occurring oxygen bonds with the metal. Oxidation is a form of corrosion, since oxidation removes solid matter.
What chemical reaction produces both corrosion and iron oxide in the soil?
Corrosion is an oxidation reaction.
What tarnishes pennies?
Oxidation and corrosion tarnish pennies
What is ment by corrosion?
The oxidation of iron, usually undesired.
What is another word for corrosion?
eroding, caustic
What do you call it when iron oxidises?
Corrosion is the oxidation of metals in general. Rusting is the oxidation of iron in particular.
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.
What do you call a slow oxidation reaction involving metals?
Corrosion
What does the chemical weathering called oxidation cause?
Rust. Corrosion.
Is rust a form of corrosion?
Yes. Rust is oxidation of the metal, a form of corrosion (chemical destruction) that weakens metal.
