Properties of Tin (Sn)
Tin is a chemical element with the symbol (Sn) and atomic number 50. It is a silvery-white metal that is often used as a coating for other metals to prevent corrosion. Tin is malleable, ductile, and has a relatively low melting point, making it easy to work with.
The following table provides a comprehensive list of tin (Sn) properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).
