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.
