El molibdeno es un metal de transición de alto punto de fusión, esencial para las aleaciones de acero. Es además un oligoelemento necesario para la vida.

Acerca de Molibdeno

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.
