Where and How Vanadium (V) Atomic Mass: 50.996 Atomic Number: 23

Tell me more!!


Where is Vanadium found???

Vanadium's natural abundance in the earth's crust is 0.02%(Stwertka)
Vanadium is found in over 55 different minerals. A few of the minerals that vanadium can be found in are:
Patronite (VS4)
Vanadinite [ Pb5(VO4)23H2O]
Carnolite [K2(VO2)2(VO4)23H2O]







How is it obtained???

Vanadium is obtained by heating one of the minerals in which vanadium is present, with calcium and chlorine. This will prodcue a compound called vanadium trichloride (VCl3). Once the vanadium trichloride is obtained, it is heated with magnesium in an argon atmosphere. Vanadium in vanadium pentoxide can be isolated by adding calcium to the vanadium pentoxide. The calcium will join with the oxygen leaving the vanadium alone. (Newton 650)

What is the structure of Vanadium???

Vanadium structure is made up of unit cells that are body-centered cubic, or BCC. (Winter). A body-centered cubic lattice combined of many square unit cells. Each of these cells has one complete atom located in the center and then atoms located in each of the corners. Although these corners atoms are very close, they do not touch one another. All of the atoms, however, do touch the center atom. (Watkins)

This is a picture of what the structure of a cell unit might look like.

What are the Chemical Properties and reaction tendencies??

Vanadium "has good corrosion resistance to alkalis, sulphuric acid, hydrochloric acid, and salt waters"(Winter). This element can be found among the transitional metals. It is reactive to oxygen and carbon at high temperatures (Stwertka). The reason Vanadium has so many compounds is due to the fact that Vanadium will react with most nonmetals (Haserman). Vanadium does contain a little radioactivity. The half-life of Vanadium is 3.9 x 10^17 (Handbook...).
