Vanadium

Vanadium sits in group 5 of the periodic table as a transition metal. Like many transition metals, it forms a rich variety of complex chemical compounds. Vanadium has four stable oxidation states, which are +2, +3, +4, and +5.

An oxidation state describes how many electrons an atom has naturally lost or gained. Each unique oxidation state creates a distinct, vibrant color when dissolved in liquid water. You can find vanadium naturally in about 65 different minerals across the world.

Two common examples of these vanadium-bearing minerals naturally include vanadinite and carnotite. Scientists also frequently discover this metal inside various fossil fuel deposits. The pure metal resists corrosion extremely well under normal atmospheric conditions.

It quickly forms a protective film of oxide on its outer surface. This microscopic film completely stops the underlying metal from rusting any further. Other strong metals like titanium and chromium behave in a very similar way.

Vanadium acts as an amphoteric element when it reaches its highest oxidation state. Amphoteric means the chemical can act as both an acid and a base. In this specific state, it forms both vanadate salts and vanadyl cations.

Cations are simply atoms or molecules that carry a positive electrical charge. Factories produce a massive amount of vanadium across the world every single year. They use a large portion of this metal as an additive for steel.

Adding vanadium to steel creates a much stronger and tougher metal alloy. An alloy is a solid mixture of two or more different elements. Vanadium pentoxide (V₂O₅) is another highly useful and important chemical compound.

Chemical companies frequently use this oxide as an important industrial catalyst. A catalyst is a substance that dramatically speeds up a chemical reaction. This specific catalyst helps factories produce sulfuric acid during the contact process.
