See more Indium products. Indium (atomic symbol: In, atomic number: 49) is a Block P, Group 13, Period 5 element with an atomic weight of 114.818. The number of electrons in each of indium's shells is [2, 8, 18, 18, 3] and its electron configuration is [Kr] 4d10 5s2 5p1. The indium atom has a radius of 162.6 pm and a Van der Waals radius of 193 pm. Indium was discovered by Ferdinand Reich and Hieronymous Theodor Richter in 1863. Indium Bohr ModelIt is a relatively rare, extremely soft metal is a lustrous silvery gray and is both malleable and easily fusible. It has similar chemical properties to Elemental Indiumgallium such as a low melting point and the ability to wet glass. Fields such as optics and microelectronics that utilize semiconductor technology have wide uses for indium, especially in the form of Indiun Tin Oxide (ITO). Thin films of Copper Indium Gallium Selenide (CIGS) are used in high-performing solar cells. Indium's name is derived from the Latin word indicum, meaning violet.

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.
