Iodine

Iodine is a nonmetal chemical element with the symbol I and atomic number 53. It is a heavy, non-metallic, lustrous, purplish-black solid at standard conditions that readily sublimes to form a violet gas. iodine belongs to the halogen group (Group 17) in the periodic table. It plays a vital role in human health, particularly in the production of thyroid hormones. iodine deficiency can lead to various health issues, including goiter and cognitive impairments. Its chemical properties enable it to be used as a disinfectant, a contrast agent in medical imaging, and in the production of various organic compounds and pharmaceuticals. Its unique properties result from having a full electron shell which it uses to bond strongly. The element is relatively rare and is found in various forms, including iodides in seawater and in certain minerals. It's known for its characteristic pungent odor and ability to stain organic materials.

Iodine meaning with examples

• As a vital nutrient, iodine is often added to table salt to prevent iodine deficiency disorders; consuming it can help regulate the body's metabolism through the production of thyroid hormones.

• Iodine's ability to absorb X-rays makes it a valuable contrast agent in medical imaging. It can be injected or ingested to enhance the visibility of blood vessels and other tissues during procedures like CT scans and angiography. It is used extensively in medicine.
• Iodine can also be used to create various chemical compounds and is used extensively in the production of pharmaceutical drugs. It serves as a catalyst in certain chemical reactions and is an important component in several laboratory experiments and industrial processes.
