Molybdenum is a Group 6 transition metal with the atomic number 42 and symbol Mo.

Molybdenum has unique properties that make it essential for life. This element is widely used as a solid lubricant, catalyst (especially in the oil refinery industry) and anti-corrosive pigment, and in high-strength stainless steel and high-temperature super alloys.

In addition, it is employed in electronic applications due to its magnetic properties and ability to withstand extreme temperatures without significantly expanding.
