  • MolybdenumWikipedia

    Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from NeoLatin molybdaenum, which is based on Ancient Greekmolybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered in the sense of differentiating it as a new entity from the mineral salts of
