Zinc is a metal mined in Vielle Montagne and Zinkgruvan and used for plating steel. Reacts slowly like other metals. It combines with oxygen and other non-metals and reacts with dilute acid to release hydrogen gas. It is the fourth most commonly used metal and after iron, aluminum and copper is the most produced metal. The common oxidation state of this element is +2.
