Tin is quite a rare element, occurring chiefly in the mineral cassiterite. Pure crystalline tin exists in two allotropic modifications, the metallic form （white tin）, and a semimetallic form （grey tin）. It is used in various alloys, notably bronze, and for electroplating iron or steel sheets to make tinplate.
