Atomic Number: 40

Protons: 40

Electrons: 40

Neutrons: 51

Average Atomic Mass: 91.224

Isotopes: Zr-90, Zr-91, Zr-92, Zr-94, Zr-96

Discovery: Zirconium was discovered by Martin Heinrich Klaproth in 1789 at Berlin,Germany

Name: From the Arabic word "zargun" meaning "gold color"

Uses:The metal is used in the nuclear industry for cladding fuel elements since it has a low absorption cross section for neutrons. Zirconium is very resistant to corrosion by many common acids and alkalis and by sea water.

Interesting Facts: If you weigh 105 pounds and measure it in kilograms you weigh about 0.00525 grams of zirconium. If you calculate it in pounds your 0.0023835
