Zinc has been known since prehistoric times and is named 'Zinc' German word "zin" meaning "tin".

Some common usages for Zinc: metal coating, rust protection, brass, bronze and nickel.

Definitions and Notes

Density listed is at a temperature of 20°C.

Isotopes are forms of an element who have the same atomic number but different mass because they contain different number of neutrons.

Half-life is the time required for a quantity of a subject to fall to half of its current quantity.
