What Does Zinc (Zn) Mean?

Zinc (Zn) is an important chemical element with a silver grey appearance that has the ability to sacrifice itself to protect a metallic object from corrosive attack. The atomic number of zinc is 30 and it is present as a first element in group 12 of the periodic table. Zinc exists naturally in the air, water and soil.


Corrosionpedia Explains Zinc (Zn)

Zinc is the 24th most abundant element in the Earth's crust and consists of five stable isotopes: zinc 64, zinc 66, zinc 67, zinc 68 and zinc 70. Zinc 64 (64Zn) is most abundant of the isotopes (approximately 48.6%).

Zinc is predominantly used to protect steel from corrosion and is applied on steel surfaces as a zinc coating or in some other form. Zinc is used in the hot dip galvanizing process, in which it is used as a sacrificing agent to protect a metallic surface.
