this is because as long as a layer of oxide of zinc or tin is present the steel article does not get exposed to air but when it gets removes,the steel reacts with air/oxygen to form its oxide.

Answer:
Zinc is more reactive than steel while tin is less reactive than steel.
Explanation:
When the zinc layer is damaged the surrounding atoms would be attracted to the zinc and therefore only react with the zinc and not the steel (zinc is basically like a magnet). When tin is damaged the atoms would react with steel because steel is more reactive. Atoms rather react with a more reactive element.
