Iodine is a chemical element that comes with the symbol I and has its atomic number 53. It is the most heaviest of stable halogens and exits as a lustrous, metallic solid at standard states, which sublimes promptly to form a violet gas. The element occurs in various oxidation states, including iodide and iodate. Additionally, it also exists in different periodate anions. Being least copious of the stable halogens, it is the heaviest indispensable mineral nutrient. Iodine is the fourth halogen, which is similar to other halogens is a powerful oxidising agent, which make reaction with various elements so as complete its outer shell.
Benefits and usages:
- This weakest oxidizing comes with lowest electronegativity and is utilized in various applications of varied importance.
- Used for organoiodine compounds, pure element, make potassium iodide, and inorganic iodine compounds.
- Other major utilization of this compound are catalysts, stabilizers, dyes, animal feed supplements, pigments, pharmaceutical, photography, colorant and sanitation.
- Minor utilization include cloud seeding, smog inhibition, and different other uses in analytical chemistry.
