Molybdenum Element Cube

Molybdenum's atomic number is 42 and its symbol is Mo. Molybdenum’s name comes from the ancient Greek word for “lead” because for a long time because molybdenum ore was confused with lead ore. About 80% of the world's production of molybdenum is used to create high strength or super alloys of steel. What sets this element apart is how little it expands at high temperatures. This ability makes it valuable in extreme heat applications such as military armor, aircraft parts, electrical contacts, or support filaments in light bulbs.
