(Source:Mineral Information Institute)  Molybdenum is a
metallic, silvery-white element, with an atomic number of 42.
Its chemical symbol is Mo. Chemically, it is very stable, but it
will react with acids. The physical characteristic that makes
molybdenum unique is that it has a very high melting point at
4,730 degrees Fahrenheit. This is 2000 degrees higher than the
melting point of steel. It is 1,000 degrees higher than the
melting temperature of most rocks. It has the fifth highest
melting point of all of the elements.       Previous Element:
