- -[ Molybdenum ]-[ Atomic number: 42 ]-[ Chemical symbol: Mo ]-
-  
- Molybdenum has been known throughout history, though its
- properties meant that it was confused with lead ores. It was
- first identified as a distinct element in 1778, meaning our
- modern understanding of its existence reaches about as far
- back as American independence.
-  
- Molybdenum has a very high melting point, 2623°C, the fifth-
- highest temperature of any element.
-  
- While pure molybdenum is only about as strong as tooth enamel,
- it forms strong alloys that are resistant to corrosion and
- stable under varying temperatures. As a result, these alloys
- are used for metal armour plates, high-performance aircraft
- parts, and pumps for molten metal flows.
-  
- In its elemental form, it can be used as a fertiliser, and the
- isotope molybdenum-99 is used as a source of technetium-99m,
- an important medical radioisotope used for 3D bone scans and
- the investigation of blood flow when diagnosing heart disease.
