Tin, periodic table Sn, is a metal, atomic number 50. It's most common isotope is 120Sn (32,58%) ,with 70 neutrons. The Latin name is Stannum.
Tin is a soft and ductile metal, often alloyed (proportion of 12%) with copper to create bronze.
Tin is quite dilute in the Earth crust (2 ppm), and probably the Martian crust as well. Concentration may have taken place through erosion processes, but exploration is needed. On Earth Tin is usually present as an oxide (SnO2) in granite formations.
