  • Zinc is a chemical element with the symbol Zn and atomic number 30.

  • Another name for zinc, in non-scientific terms, is "spelter".

  • Pure zinc is a shiny bluish-white colored metal, while commercial grades of the metal usually have a dull finish to it.

  • Zinc is the 24th most abundant element in the Earth's crust.

  • The melting point of zinc is 787.1 °F (419.5 °C) and the boiling point is 1,664.6 °F (907 °C).

  • Brass is a zinc and copper alloy that has been used by humans since ancient times. Zinc metal however, was first produced on mass in 12th century India. While Europe did not know about zinc metal until the end of the 16th century.

  • An important quality of zinc is its ability to resist corrosion and therefore protect other metals. Half of all zinc produced today is used to galvanize steel to prevent against corrosion. It is used to protect buildings, cars, nails, wire, pipes and more.

  • Zinc compounds such as zinc oxide are found in many common commercial products, including batteries, paint, plastics, rubber products, pharmaceuticals, floor coverings, inks, cosmetics, soap, and textiles. Zinc is also a natural insect repellent and sun screen, helping to protect our skin.

  • Zinc is an essential nutritional mineral for humans and animals alike. After iron, it is the second most common trace metal found naturally in our bodies.

  • Zinc deficiency is associated with many diseases and is believed to affect around 2 billion people in the developing world.

  • Even though zinc is an essential requirement for good health, excess zinc can be harmful, suppressing copper and iron absorption. The U.S penny coin is made of 97.5% zinc and there have been cases of zinc toxicity after humans and dogs ingested the coins.

  • In 2010, China produced nearly a third of the global zinc output. Other notable zinc mining countries include Australia and Peru.

  • After iron, aluminium, and copper, zinc is the fourth most common metal we use today.

  • Around 70% of the world's zinc comes from mining, the remaining 30% comes from recycling the metal because zinc is 100% recyclable.
