What is the atomic symbol for iodine?

Iodine is a chemical element that is represented by the atomic symbol "I" on the periodic table. Each element is assigned a unique one- or two-letter symbol that is derived from its English or Latin name. In the case of iodine, the symbol "I" comes directly from the name itself. This symbol is key for identifying iodine in chemical formulas, reactions, and discussions related to chemistry and biology. Understanding the symbols is essential for interpreting scientific literature and for engaging in lab work where elements are denoted by their symbols rather than their full names.
