Neodymium essays My elements name is Neodymium. Neodymium was discovered in 1925 by C.F. Aver von Welsbach in Austria. This element got its name from the Greek words neos, which means new, and didymos, which means twin. Nd is the atomic symbol and it is in group IIIA, which is the rare earth elements or the Lanthanide Series. The price for Neodymium is about $1/g. Neodymium has a popularity of 16 out of 100. The atomic weight of Nd is 144.24 amu. It is white, yellow, or brown. It has a hexagonal shape. It has 60 Protons, 84 Neutrons, and 60 electrons. Neodymiums melting point is 1010.0 C, 1283. 15Â °K, and 1850.0F. Its boiling point is 3127.0C, 3400.15Â °K, and 5660.6F. Neodymium is a solid. The oxidation number is +3. Neodymium is never found in nature as a free element, it is found in ores monazite sand. It is mostly used for making magnets. Neodymium is used for to make many different things. It makes up about 18% of Misch metal, a material that is used to make flints for lighters. Neodymium is also a component of didymium glass, which is used to make certain types of welder's and glass blower's goggles. Neodymium is added to glass to remove the green color caused by iron contaminants. It can also be added to glass to create violet, red or gray colors. Some types of glass containing neodymium are used by astronomers to calibrate devices called spectrometers and other types are used to create artificial rubies for lasers. Neodymium salts are also used to color enamels and glazes in ceramics and for a special lens with praseodymium. Nd is also used to produce bright purple glass and special glass that filters infrared radiation. There is also a lot of Neodymium can be found in magnets and stained glass. Neodymium is present in misch metal to the extent of about 18%. The metal has a bright silvery metallic lustre. Neodymium is one of the more reactive rare-earth metals and ...
