Zinc is a hard, brittle metal. It is most commonly used mixed with other metals to make alloys like brass, and as a coating on other metals to stop them rusting. Zinc stops other metals rusting because when it is attached to another metal it will rust before that other metal does. The other metal will then start to rust when all the zinc is gone.
Metal that is coated with zinc is called galvanized. If you look closely at galvanised metal you can see the zinc crystals.
