Tin Bohr ModelSee more Tin products. Tin (atomic symbol: Sn, atomic number: 50) is a Block P, Group 14, Period 5 element with an atomic weight of 118.710. The number of electrons in each of tin's shells is 2, 8, 18, 18, 4 and its electron configuration is [Kr] 4d10 5s2 5p2. The tin atom has a radius of 140.5 pm and a Van der Waals radius of 217 pm.In its elemental form, tin has a silvery-gray metallic appearance. It is malleable, ductile and highly crystalline. High Purity (99.9999%) Tin (Sn) MetalTin has nine stable isotopes and 18 unstable isotopes. Under 3.72 degrees Kelvin, Tin becomes a superconductor. Applications for tin include soldering, plating, and such alloys as pewter. The first uses of tin can be dated to the Bronze Age around 3000 BC in which tin and copper were combined to make the alloy bronze. The origin of the word tin comes from the Latin word Stannum which translates to the Anglo-Saxon word tin.
