-[ 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.
