The largest application of tin is in solders, included in many of today's electronic products and components. The world's most significant tin resources can be found in China and Indonesia, with some production in Central Africa. Tin is covered by regulations related to "conflict minerals" in the United States and the European Union.
Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table. Tin is obtained chiefly from the mineral cassiterite, where it occurs as tin dioxide, SnO2. This silvery, malleable poor metal is not easily oxidized in air and is used to coat other metals to prevent corrosion.
Tin have atomic number 50 and atomic mass 118,71, commonly found as cassiterite in nature. It is one of important elements in low carbon technologies.
