Zinc is a type of metal that's used to make brass. Zinc is also present in some of the food we eat, and it's important for helping our bodies fight off bad bacteria and viruses.
In its basic form, zinc is a brittle, bluish-white metal. Along with copper, it's used to make the brass for light fixtures, doorknobs, and tools, among many other things. Pennies contain zinc too — since 1982, they contain 97.5% zinc and 2.5% copper. There's also zinc in our bodies, and in food including shellfish, meat, and seeds. The word zinc is believed to come from the German Zinke, "point," in reference to the spiked shape of a zinc crystal.
