Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes.
What is Zinc? Zinc is the primary component of the hot-dip galvanized coating. But to only recognize zinc as it is used in the galvanizing process would be a huge disservice to the natural, healthy metal. The silvery, blue-gray vital metal is abundant, essential, and common â and even more importantly infinitely recyclable.
