Which element has the symbol 'I'?

Which element has the symbol 'I'?

• A. Helium
• B. Neon
• C. Iodine
• D. Krypton

Answer: (C)

The symbol 'I' represents the element iodine on the periodic table. Iodine is a halogen and has the atomic number 53. It is well-known for its role in the human body, particularly in thyroid function, where it helps in the production of thyroid hormones. Iodine can be found in various forms in nature, most notably in the form of iodide in seawater and certain foods. Understanding the periodic table is crucial in chemistry, as each element has a unique symbol that helps identify it. Helium, neon, and krypton, while they are all noble gases, have distinct symbols which are different from iodine, making it essential to be familiar with each element's symbol and properties. This knowledge aids in grasping various chemical concepts and is fundamental for further studies in science disciplines.
