Understanding The Charge And Chemical States Of Iodine: Its Impact On Reactivity And Biological Functions
The charge of iodine depends on its chemical state: as an atom, it is neutral; as an ion, it typically carries a -1 charge (I⁻). This negative charge results from the gain of an electron, which fills the outermost electron shell of the iodine atom and makes it stable. Iodine’s electronegativity, or tendency to attract…
