Zinc Element in Periodic Table | Atomic Number Atomic Mass
Zinc is a chemical element and it is a member of group 12 and period 4 in the periodic table. The atomic number of zinc is 30 and it is indicated by symbol Zn. Zinc is a bluish-white, lustrous, diamagnetic metal. Zn is the 24th most abundant element in Earth’s crust and has five stable isotopes. Zn is chemically similar to magnesium. 64Zn is the most abundant isotope and 66Zn, 67Zn and 68Zn are the other isotopes found in nature.
Uses of Zinc Element:
- Zn is used in alloys such as brass, nickel, silver and aluminium solder.
- Zinc is used to galvanise other metals such as iron to prevent rusting.
- Zinc oxide is also used in the manufacture of products such as paints, rubber cosmetics, plastics, soaps, inks, textiles, batteries, pharmaceuticals and electrical equipment.
- Zinc sulphide is used in making luminous paints, x-ray screens and fluorescent lights.
