Definition of the Molybdenum Element
A hard, silvery-white metallic element used to toughen alloy steels and soften tungsten alloy. An essential trace element in plant nutrition, it is used in fertilizers, dyes, enamels, and reagents.

Origin / Meaning of the name Molybdenum
The name Molybdenum originates from the Greek word molubdos meaning "lead-like"

Classification of the Molybdenum Element
Molybdenum is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. An Element classified as a Transition Metals is ductile, malleable, and able to conduct electricity and heat.

The Discovery of Molybdenum
Molybdenum was discovered by Carl Wilhelm Scheele  in 1778

Facts about the History of the Molybdenum Element
The Russian Luna 24 mission discovered a single grain of pure Molybdenum in a pyroxene fragment taken from Mare Crisium on the Moon.

Occurrence the Molybdenum Element
Obtained from molybdenite, powellite and wulfenite
Found in the enzyme xanthine oxidase
Byproduct of copper mining
Mined in the USA

Associated Uses of Molybdenum
High strength alloys
High temperature steels
Aircraft parts
Missile parts

Molybdenum and the Periodic Table
Check out Molybdenum on the Periodic Table which arranges each chemical element according to its atomic number, as based on the periodic law, so that chemical elements with similar properties are in the same column. Our Periodic Table is simple to use - just click on the symbol for Molybdenum for additional information and for an instant comparison of the Atomic Weight, Melting Point, Boiling Point and Mass - G/cc with any other element. An invaluable source of facts and information as a Chemistry reference guide.

Molybdenum - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Molybdenum is just one element that can be found.
