About Niobium

Niobium (Nb) is a soft, ductile transition metal, atomic number 41, occupying group 5 of period 5 in the periodic table's d-block. Its electron configuration is [Kr] 4d⁴ 5s¹, and it carries a moderate electronegativity of 1.6 on the Pauling scale. Niobium's principal value lies in metallurgy: it strengthens high-strength low-alloy steels, allowing lighter and tougher structural components, and it is a key constituent of the niobium-titanium and niobium-tin alloys used to wind superconducting magnets. With an atomic mass of 92.91, it sits between zirconium and molybdenum among the second-row transition elements. The metal remains solid at standard temperature and pressure and resists corrosion through a stable surface oxide.
