Consider the following statements regarding Vanadium: It is a silver-g...
Vanadium, a critical raw material for many industrial applications, has been found recently in sediment samples collected from the Gulf of Khambhat in Gujarat.
About Vanadium:
- It is a chemical element with the symbol "V" and atomic number 23.
- It is a silver-grey, ductile, and malleable metallic element.
- It is harder than most metals and exhibits good corrosion resistance against alkalis and acids.
- History:
- It was discovered (1801) by the Spanish mineralogist Andrés Manuel del Río, who named it erythronium but eventually came to believe it was merely impure chromium.
- The element was rediscovered (1830) by the Swedish chemist Nils Gabriel Sefström, who named it after Vanadis, the Scandinavian goddess of beauty and youth.
- The English chemist Henry Enfield Roscoe first isolated the metal in 1867 by hydrogen reduction of vanadium dichloride.
- Occurrence:
- Found combined in various minerals, coal, and petroleum, vanadium is the 22nd most abundant element in Earth’s crust.
- It is found in over 60 different minerals, including vanadinite, carnotite, roscoelite and patronite.
- The largest resources of vanadium minerals are found in South Africa and Russia.
- Leading Producers: China, South Africa and Russia.
- Applications:
- Alloys:
- One of the primary uses of vanadium is as an alloying element in steel and other metals.
- Vanadium steel, for example, is known for its strength, toughness, and ability to maintain hardness at high temperatures. It is commonly used in tools, cutlery and structural materials.
- In Vanadium Flow Batteries (VFBs), vanadium is used to create a reliable, safe and stable solution for the storage of renewable energy.
- Chemical Catalysts: Vanadium compounds are used as catalysts in various chemical reactions, such as the production of sulfuric acid.
- Nuclear Applications: Vanadium is used in some nuclear reactors as a structural material and neutron moderator.
- In the medical sphere, vanadium is used to treat a number of ailments, including diabetes, heart disease and high cholesterol.
Hence both statements are correct.

Consider the following statements regarding Vanadium: It is a silver-g...
Statement 1: It is a silver-grey metallic element.
Vanadium is indeed a silver-grey metallic element. It is classified as a transition metal and is represented by the chemical symbol V. It has an atomic number of 23 and an atomic weight of 50.9415. Vanadium is known for its high melting point, strength, and low thermal conductivity. It is commonly found in minerals such as vanadinite and carnotite.
Statement 2: It exhibits good corrosion resistance against alkalis and acids.
This statement is also correct. Vanadium exhibits good corrosion resistance against both alkalis and acids. It is often used as an alloying element in stainless steel to improve its resistance to corrosion by various chemicals. Vanadium forms a protective oxide layer on its surface when exposed to air or moisture, which helps to prevent further corrosion.
Explanation:
Vanadium is a versatile element with various industrial applications. It is used in the production of steel, where it imparts strength and corrosion resistance. Vanadium steel is commonly used in tools, surgical instruments, and other applications that require high strength and durability.
In addition to its use in steel production, vanadium is also used in the manufacturing of batteries, particularly in vanadium redox flow batteries. These batteries have a high energy density and can be efficiently charged and discharged multiple times, making them suitable for renewable energy storage.
Vanadium compounds are also used in the production of ceramics, pigments, and catalysts. For example, vanadium pentoxide is used as a catalyst in the production of sulfuric acid. Vanadium compounds are also used in the production of glass, as they can impart certain colors and improve the chemical durability of the glass.
In conclusion, both statements given are correct. Vanadium is a silver-grey metallic element and exhibits good corrosion resistance against alkalis and acids. Its unique properties make it a valuable element in various industries.
