Zinc (Zn) is a bluish-gray, lustrous, metallic element in group 12 of the periodic table (Fig 2). It is an anomalous transition element.. Zinc occurs naturally as the ores sphalerite, smithsonite, hemimorphite, and wurtzite, and is extracted by roasting to the oxide and reduction with carbon.. Zinc is brittle at room temperatures but malleable when heated.
