- Molybdenum (Mo) is a chemical element in the periodic table with atomic number 42, discovered by Carl Wilhelm Scheele in 1778. Its name is derived from the Greek word Molybdos which means lead.
- It is a silvery white, hard transition metal and has one of the highest melting points of all pure elements.
- It can be attacked slowly by acids.
- Molybdenum is known to have 35 different isotopes varying in atomic mass from 83 to 117.
- It is one of the greatest alloying agents as it improves the strength of steel at high temperatures and is applied for use in engines.
- It is even used as a fertilizer for some plants like cauliflower which is known to have Molybdenum deficiency.
- It is used as a catalyst for the petroleum industry.
