Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. It is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, SnO2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magic number of protons. It has two main allotropes. At room temperature, the stable allotrope is β-tin, a silvery-white, malleable metal. However, at low temperatures, it transforms into the less dense grey α-tin, which has a diamond cubic structure. Metallic tin is not easily oxidized in the air.
