"In chemistry, a molybdate is a compound containing an oxoanion with molybdenum in its highest oxidation state of 6: O −Mo(=O)2−O . Molybdenum can form a very large range of such oxoanions, which can be discrete structures or polymeric extended structures, although the latter are only found in the solid state. The larger oxoanions are members of group of compounds termed polyoxome… " - How is molybdenum formed
