In theory, 10 mg of iodine (I2), if all converted to iodide (I), would yield 10 mg of iodide (I-). (1) iodine (3) strontium (2) silver (4) xenon. Iodine ions are unintentionally incorporated when the crystals are grown by the chemical-vapor-transport method with SnI 4 as the transport agent. When you are working with ionic compounds (they are called ionic because they consist of ions) you'll often need to determine the ionic charge.This is especially the case when you are writing formulas based on the chemical name. Addition of potassium iodine results in a reversible reaction of the iodine ion with iodine to form a triiodide ion, which further reacts with an iodine molecule to form a pentaiodide ion. Since it can have more than 8 electrons for its outermost shell (really crazy stuff about atomic orbitals! whosethatgurl101.
