**Symbol:** Zn **Atomic number:** 30 **International name:** Zinc **Relative Atomic Weight:** 65.38 **Description:** Zinc is a soft, shiny, silver-white metal. It is stable in air due to the formation of a protective oxide layer, a process known as passivation. **Applications:** Zinc is used in galvanizing steel and iron sheets to prevent rusting. It is also used in the production of alloys, such as brass (Cu + Zn). **Occurrence:** Zinc is relatively abundant in the Earth's crust. Its most important mineral is sphalerite (ZnS). **Structure:** Zinc crystallizes in a hexagonal crystal system with a primitive unit cell structure.
