Acerca de Yodo

Iodine (I) is a halogen essential to human health, required by the thyroid gland to synthesize hormones that regulate metabolism. Element 53 sits in group 17 of period 5 in the p-block, with an atomic mass of 126.9, the electron configuration [Kr] 4d¹⁰ 5s² 5p⁵, and a high Pauling electronegativity of 2.66. Solid at standard conditions, it readily sublimes to a violet vapor, a behavior unusual among the elements. Iodine and its solutions are valued as antiseptics and disinfectants, and it is the heaviest of the common, stable halogens, sitting below chlorine and bromine in the group.
