Iodine - Wikipedia
网页Most metal iodides with the metal in low oxidation states (+1 to +3) are ionic. Nonmetals tend to form covalent molecular iodides, as do metals in high oxidation states from +3 and above. Both ionic and covalent iodides are known for metals in oxidation state +3 (e.g. scandium iodide is mostly ionic, but aluminium iodide is not).

Iodine - Element, Halogen, Gas | Britannica - Encyclopedia Britannica
网页2024年9月5日 · The first ionization potential of the iodine atom is considerably smaller than that of the lighter halogen atoms, and this is in accord with the existence of numerous compounds containing iodine in the positive oxidation states +1 (iodides), +3, +5 (iodates), and +7 (periodates). Iodine combines directly with many elements.
Iodization of salt for the prevention and control of iodine …
网页2023年8月9日 · Iodization is the process of fortifying salt for human consumption with iodine and is an effective strategy to increase iodine intake at the population level. The public health goals of reducing salt and increasing iodine intake through salt iodization are compatible as the concentration of iodine in salt can be adjusted as needed.
