Tin itself is highly resistant to rusting (oxidation) so the tin coating remains intact. Oxygen molecules are therefore unable to reach the iron layer beneath, making it impossible for the iron to rust.
As tin is not reactive with water or oxygen rusting cannot occur as these two substances are needed for rusting to occur
Tin plating prevents rusting as metals can be coated with other metals which are less likely to corrode. Food cans are steel cans dipped into molten tin giving a layer of tin.
It prevents rust because it acts like a shield repeling water and oxygen from touching the metal underneth
Coating prevent the iron from contacting air and moisture. So it prevents iron from rusting.
The direct contact of iron with air and moisture is avoided.
To prevent it from reacting with oxygen and rusting.
You use chrome plating which is shiny and attractive and lasts a long time even though it is very expensive

Aye
In terms of the rusting of iron/steel objects - exclude oxygen and moisture. Coating iron objects with a layer of oil, grease or paint is the easiest. Keeping them in a dry and inert atmosphere is another, but not so easy or practical. A common technique is coating them with a layer of Tin or Zinc plating, which is generally referred to as "cathodic protection", where the layer of Tin or Zinc will corrode preferentially to prevent rusting. Plating with Copper or Chromium is similar to painting in so far as the iron/steel is protected from oxygen or moisture, but only so long as the plating is unbroken, otherwise it may actually promote rusting.
Iron can are electroplated with tin to prevent the cans from rusting. Tin is a metal that resists rust.
Because plastic containers have a tendency to melt and catch fire.

Electrolysis can be used to prevent rusting because metals give away electrons and if the metal is wired up to the negative electrode it gains electrons which means it will prevent rusting as it isn't losing electrons.
They're not - or not any more. When it was done (a century ago) it was to prevent the steel of the cans from rusting.
Tin is an element, but you have to be careful because many people use the term loosely. They sometimes mean simply 'metal' and sometimes iron coated with tin to prevent rusting, and by extension, iron coated with anything else.
