Rust is the oxidation of iron.
Metals will react with oxygen but only iron'rusts'.
Aluminium oxidises but it forms an impermeable oxide layer on the aluminum which prevents further oxidation.
Zinc has a stronger affinity for oxygen than iron. Zinc is used to coat iron in a process known as galvanising. The zinc oxidises preventing the iron from rusting. The zinc actually forces the iron to keep its electrons rather than losing them to oxygen.
2Fe(s) + 3O2(g) --> 2Fe2O3(s)
2Zn(s) + O2(g) --> 2ZnO(s)
When iron and zinc are together:
Zn(s) + Fe2+ --> Zn2+ + Fe(s)

Is corroding metal a chemical change?
Yes. When metal rusts the iron is changed into iron oxide. This type of change is called a redox reaction. The iron is oxidized, meaning is has lost electrons.
Why is most Iron in the world not found as the metal?
Iron rusts.
What is a hard silver-white magnetic metal easily rusts in moist air?
This metal is iron.
Is metal still a metal after it rusts?
There is only one metal that rusts and that is iron and its alloys such as steel. All other metals corrode. No, iron is not iron after it rusts. It is now called iron oxide and will disintegrate if left unchecked . That is why we paint our gates with Blackstar Rust Converter and most electronics are coated with gold or a green varnish to prevent reaction with the air.
What metal never rusts or lose its shine or tarnish?
which material does not loses its shine. Is gold
Is metal rust bad for trees?
Metal rust will not harm trees. There are a number of fungus rusts that can harm plants but they are not metal rusts.
If metal rusts is it the same metal?
The rust is an oxide of the base metal.
What transition metal rusts when exposed to oxygen?
Iron rusts in the presence of Oxygen.
Is metal corroding chemical change?
Yes. When metal rusts the iron is changed into iron oxide. This type of change is called a redox reaction. The iron is oxidized, meaning is has lost electrons.
When a part rusts does it become Heavier or lighter in weight?
When metal rusts by forming a solid metal oxide with oxygen from air, the rusted solid metal weighs more.
Is corroding metal a chemical change?
Yes. When metal rusts the iron is changed into iron oxide. This type of change is called a redox reaction. The iron is oxidized, meaning is has lost electrons.
Does saltwater affect the rate metal rusts?
Yes it does!
What happens when a metal fork rusts?
physical change
Which metal rusts first copper or iron?
Neither. Only iron rusts. Other metals oxidize.
What is the reason why nails rust in water?
They're metal and metal rusts because the iron in metal oxidizes.
What scientifically happens to metal when it rusts?
a chemical change occurs
Why is most Iron in the world not found as the metal?
Iron rusts.
