About Vanadium

Notable for the vivid colors of its compounds, vanadium is a hard, silvery-grey transition metal that adopts several oxidation states. It has atomic number 23 and an atomic mass of 50.942, a density of 6.11 g/cm³, and a melting point of 2183 K. Its [Ar] 3d3 4s2 configuration gives an electronegativity of 1.63 and a first ionization energy of 651 kJ/mol. Andrés Manuel del Río first encountered the element in 1801. Added in small amounts to steel, vanadium greatly increases strength and toughness, which is its principal industrial use. Its many accessible oxidation states make its solutions strikingly varied in color. Vanadium occupies group 5, period 4.
