Propulsion systems employing iodine as the propellant can be built more compactly, with less mass (and cost), and operate more efficiently than the gridded ion thrusters that were utilized to propel previous spacecraft, such as Japan's Hayabusa probes, ESA's GOCE satellite, or NASA's DART mission, all of which used xenon as the reaction mass. In these technologies, which support the world's demand for acetic acid, hydroiodic acid converts the methanol feedstock into methyl iodide, which undergoes carbonylation. But seriously: anions and cations are both ions. To achieve an octet of valence electrons, an iodine atom will become an ion with what charge? Iodide Iodide is a halide anion and a monoatomic iodine. The number of electrons gained, and so the charge of the ion, is indicated after the chemical symbol, e.g. When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same number of electrons as an atom of the next noble gas in the periodic table.
