Molybdenum is a high-melting-point transition metal essential for steel alloys. It is also a trace element necessary for life.

About Molybdenum

Distinguished by an unusually high melting point among the transition metals, molybdenum (Mo) is element 42, positioned in group 6 of period 5 within the d-block. Its refractory character makes it valuable in steel alloys, where it improves strength, hardenability, and resistance to heat and corrosion. Molybdenum is also a biologically essential trace element, serving as a cofactor in enzymes vital to living organisms. The metal has an atomic mass of 95.95 and the electron configuration [Kr] 4d⁵ 5s¹, with a Pauling electronegativity of 2.16. A solid at standard conditions, it lies directly below chromium in the periodic table and shares that group's tendency toward multiple oxidation states.
