Neodymium(III) 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 Neodymium's shells is 2, 8, 18, 22, 8, 2 and its electron configuration is [Xe] 4f⁴ 6s². The neodymium atom has a radius of 181 pm and a Van der Waals radius of 229 pm. Neodymium was first discovered by Carl Aer von Welsbach in 1885. In its elemental form, neodymium has a silvery-white appearance. Neodymium is the most abundant of the rare earths after cerium and lanthanum. Neodymium is found in monazite and bastnäsite ores. It is used to make high-strength neodymium magnets and laser crystal substances like neodymium-doped yttrium aluminum garnet (also known as Nd:YAG). The name originates from the Greek words neos didymos, meaning new twin.
