Acerca de Hierro

Iron is the most widely used of all metals and the principal ingredient of steel. This transition metal has atomic number 26 and an atomic mass of 55.845, a density of 7.87 g/cm³, and a melting point of 1811 K. Its [Ar] 3d6 4s2 configuration yields an electronegativity of 1.83 and a first ionization energy of 763 kJ/mol. Known and worked since antiquity, iron has no single discoverer. The element is also essential to biology, carrying oxygen in the blood as the metal center of hemoglobin. Combining strength with low cost, it sits in group 8, period 4, among the transition metals.
