Zinc Facts
Zinc (Zn) has an atomic number of thirty, and thirty protons in the nucleus of a zinc atom. It is a member of the metal group, but is a vital nutrient in both plants and animals.
Interesting Zinc Facts:
Zinc is the 24th most common element in the planet's crust.
It makes up approximately seventy-five parts per million, or .0075%, of the Earth's crust.
Zinc is also found in Earth's seawater, at around thirty parts per billion.
Zinc is usually found with other elements like copper.
It has five naturally occurring stable isotopes.
The most common stable isotope of zinc is Zn-64.
Zn-64 has such a long half-life that it radioactive properties are virtually non-existant.
It has been in use by workman and artisans since at least 1000 BC.
One statue made of more than 87% zinc found in modern-day Romania dates back to prehistory.
Writings from as early as 400 BC mention a silvery metal that was used to make brass, most likely, zinc.
Zinc was likely given its name by Paracelsus.
Andreas Sigismund Marggraf is typically given the credit for having discovered zinc's pure metallic form in 1746.
Many scientists were reported to have worked on experiments with zinc and zinc oxide as early as the late 1600s.
Zinc is used in the production of brass, where it's alloyed with copper, and many other alloys.
It is also used in plating iron, due to its non-corrosive properties.
Zinc is a hard metal, but becomes very malleable above 100 degrees Celsius.
Of all the transition metals, it has the lowest melting point after cadmium and mercury.
Zinc is considered to be a fairly strong reducing agent, and tarnishes very quickly.
Zinc burns with a very bright blue-green flare.
Zinc compounds are not very abundant.
After copper, aluminium, and iron, zinc is the most commonly used metal by industry.
Zinc production today is from nearly 70% mining and 30% recycling.
Almost all zinc (95%) is mined from sulfide ore deposits.
