Vanadium-51 Please visit the Vanadium element page for information specific to the chemical element of the periodic table. Vanadium In its 1961 report, the Commission accepted Ar (V) = 50.942 based on mass-spectrometric data, and in 1969 recommended a more precise Ar (V) = 50.9414 (3). A number of determinations of the isotopic composition of vanadium have since been considered. As a result, in 1977 the Commission refined Ar (V) to 50.9415 (1). Vanadium Vanadium is a chemical element with symbol V and atomic number 23. Classified as a transition metal, Vanadium is a solid at room temperature.

Sources of Vanadium:
Found in the minerals patronite (VS4), vanadinite [Pb₅(VO₄)₃Cl], and carnotite [K₂(UO₂)₂(VO₄)₂.3H₂O]. Vanadium is usually produced as a by-product of refining other ores and from Venezuelan oils. Annual world wide production is around 7,000 tons.
Uses of Vanadium:
It is mixed with other metals to make very strong and durable alloys which are used in construction materials, tools, springs and jet engines. Vanadium pentoxide (V2O₅) is used as a catalyst, dye and color-fixer.
Additional Notes:
Many sources credit Nils Sefström with discovering vanadium in 1831, however, this is more of a rediscovery as it had already been discovered in A.M. del Rio in 1801.
