錫 (tin) is a chemical element with the symbol Sn and atomic number 50. It is a silvery-white metal that is malleable and ductile, meaning it can be easily shaped and stretched. Tin is commonly used in alloys, such as bronze, and for coating other metals to prevent corrosion. In addition to its use in alloys, tin is also important in the production of tin cans for food preservation. It has a low melting point, making it easy to work with in various applications. Tin compounds, like stannous fluoride, are used in dental care products for their protective properties.
