Metalic crystals consists of metal cations surrounded by large number of mobile valence electrons, these electrons are also known as delocalised electrons, which do not belong to any one atom, but are capable of moving through the crystal.As a result metallic crystals are good conductors of electricity. Melting point 3400℃. Classification of tungsten ores; Tungsten ores; Tungsten does not occur naturally in its pure metallic state; rather, it is found in several ores, but only two kinds of tungsten-bearing mineral rocks, called wolframite and scheelite, are mined commercially. Its important ores include scheelite, and wolframite, lending the element its alternate name.
