Zinc is a with the atomic 30 and the symbol Zn. At room , zinc is a somewhat brittle with a silvery-greyish look when oxidation is eliminated. It is the first in periodic table group 12 (IIB). Zinc is chemically similar to in various ways: both metals have just one normal oxidation (+2), and the Zn2+ and Mg2+ions are of comparable size. Zinc is the 24th most abundant  in 's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in , , and the . Zinc is refined by froth flotation of the ore, roasting, and final extraction using  (electrowinning).
