Molybdenum is a transition metal. It is represented
by the symbol Mo. It is a pure metal that is is
silverish white in color and very hard, and has one of
the highest melting points of all pure elements at
4753 oF. Its boiling point is 8382 oF. Its density is
10280 kg/m3 and its hardness is 5.5. It has a molar
volume of 9.38 Ч10-6 m3/mol.
Molybdenum has an atomic weight of 95.94 amu. Its
atomic number is 42. The atomic radius is 145 pm and
the covalent radius is 145 pm also. Its electron
configuration is [Kr]4d^5 5s^1. It is a strong acid.
Its crystal structure is body centered cubic.
Over 2/3 of all molybdenum is used in alloys.
Molybdenum use increased a lot during World War I,
when demand for tungsten made tungsten rare, and
strong steels were at expensive. Molybdenum is used in
aircraft and missile parts, and in filaments.
Molybdenum acts as a catalyst in the petroleum
industry for removing organic sulfurs from petroleum
products.
Molybdenum is not found in nature, and the compounds
that can be found were, until the late 1700s confused
with
