Atomic Number of Iodine. Atomic Number of Iodine is 53. Chemical symbol for Iodine is I. Number of protons in Iodine is 53. Atomic weight of Iodine is 126.90447 u or g/mol. Melting point of Iodine is 113,5 °C and its the boiling point is 184,4 °C. Iodine I-131 is a radioactive isotope of iodine with an atomic mass of 131, a half life of eight days, and potential antineoplastic activity. Selectively accumulating in the thyroid gland, iodine I 131 emits beta and gamma particles, thereby killing thyroid cells and decreasing thyroid hormone production. Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure. The chemical symbol for Iodine is I. Iodine is the heaviest of the stable halogens, it exists as a lustrous, purple-black metallic solid at standard conditions that sublimes readily to form a violet gas.
