Zinc - Wikipedia

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 Zn 2+ and Mg 2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes.
