Which properties of zinc can you describe from the photo?

What are the physical properties of zinc?

Physical Properties:

Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is malleable at 100 to 150°C. It is a reasonable conductor of electricity. The density of zinc is 7.140 g/mL, which means the metal will sink in water and is relatively heavy.

What are the properties and uses of zinc?

Most zinc is used to galvanise other metals, such as iron, to prevent rusting. Galvanised steel is used for car bodies, street lamp posts, safety barriers and suspension bridges. Large quantities of zinc are used to produce die-castings, which are important in the automobile, electrical and hardware industries.
