Ultra Dry Ytterbium Bromide

See more Bromine products. Bromine (atomic symbol: Br, atomic number: 35) is a Block P, Group 17, Period 4 element. Its electron configuration is [Ar]4s²3d¹⁰4p⁵. The bromine atom has a radius of 102 pm and its Van der Waals radius is 183 pm. In its elemental form, bromine has a red-brown appearance. Bromine does not occur by itself in nature; it is found as colorless soluble crystalline mineral halide salts. Bromine was discovered and first isolated by Antoine Jérôme Balard and Leopold Gmelin in 1825-1826.

The number of electrons in each of Ytterbium's shells is [2, 8, 18, 32, 8, 2] and its electron configuration is [Xe]4f¹⁴ 6s². The Ytterbium atom has a radius of 176 pm and a Van der Waals radius of 242 pm. Ytterbium was discovered by Jean Charles Galissard de Marignac in 1878 and first isolated by Georges Urbain in 1907. In its elemental form, ytterbium has a silvery-white color. Ytterbium is found in monazite sand as well as the ores euxenite and xenotime. Ytterbium is named after Ytterby, a village in Sweden. Ytterbium can be used as a source for gamma rays, for the doping of stainless steel, or other active metals. Its electrical resistivity rises under stress, making it very useful for stress gauges that measure the deformation of the ground in the even of an earthquake.
