Vanadium, pronounced veh-NAY-di-em, atomic symbol V, and atomic number associated with this transition metal is 23. The atomic weight of Vanadium is 50.942 grams per one mole. The electron configuration is 1S2 2S2 2P6 3S2 3P6 4S2 3D3 and the noble gas notation is [Ar] 4S2 3D3. Vanadium is located in group 5B, in the transition metals, on the periodic table of the elements. Also, included in this group are niobium [atomic number 41 with an atomic weight of 92.9064 grams per mole], tantalum [atomic number 73 with an atomic weight of 180.948 grams per mole], and dubnium [atomic number 105 with an atomic weight of 262.114 grams per mole]. With a smaller density than its two counter parts, that we have data referencing, vanadium also has…show more content…
As a foil, it is used to bond titanium steel and aluminum used in jet engines and high-speed airframes. A vanadium compound, such as vanadium pentoxide (V2O5), is used as a catalyst to modify and increase the rate of chemical reaction in the ceramics industry, and in the manufacturing process of aniline black; aniline is used for resins, dyes, and varnishes. At specific temperatures, infrared radiation is blocked with glass that is coated with a vanadium compound, specifically vanadium dioxide. Additionally, as it has also a low fission neutron cross-section, a lower energy level as it splits into parts. This information, in combination with the fact that vanadium allows neutrons to penetrate easily, yet repels advances from many chemicals, makes it useful in nuclear reactor applications. This is a beneficial element and is used on a daily basis in completing routine tasks such as driving my car to school (the vanadium steel is being used in the axle and crankshaft) to school where the building was constructed, using tools that were undoubtedly made of steel that was reinforced with vanadium. Both niobium and tantalum do not react with air or water, under normal circumstances, as a thin layer of oxide protects them. While tantalum does dissolve in hydrofluoric acid and sulfuric acid, it does not appear impugned by many acids at room temperature. Likewise, niobium dissolves in hydrofluoric acid or in a mixture of nitric acid but does not perform differently
