Why is galvanised article protected against rusting even when the zinc coating is broken

Expert Answer
Because Zinc is more reactive than iron and loses electrons more easily. The outer layer of Zinc will form Zinc oxide. Which is stronger than Zinc. So even whren the zinc coating is broken it still have another strong substance ZnO which is stronger then Zinc and galvanised particles are protected from rusting.
