Zinc is a chemical element with the symbol (Zn) and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. This means that zinc can break easily if bent or twisted, and it has a metallic luster that is visible when the surface layer of zinc oxide is removed by scraping or polishing. Zinc oxide forms when zinc reacts with oxygen in the air, and it protects the metal from further corrosion.
