iodide
Let an agent explain iodides, relay chemistry, examples, nutritional and medical uses and safety from chemistry, WHO and radiation protection sources, route poisoning to emergency services and radiation emergency questions to official authorities, describe the named compounds and flag the uncertain alias, and distinguish iodides from iodine, iodates, organoiodine compounds and chlorides.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain iodides, relay chemistry, examples, nutritional and medical uses and safety from chemistry, WHO and radiation protection sources, route poisoning to emergency services and radiation emergency questions to official authorities, describe the named compounds and flag the uncertain alias, and distinguish iodides from iodine, iodates, organoiodine compounds and chlorides.
A compound containing iodine in the minus one oxidation state bonded to other elements, or the iodide ion itself, including salts such as potassium iodide, used in iodised salt and as a thyroid-blocking agent in radiation emergencies on official advice, lithium iodide in batteries, lead iodide, a yellow compound used in perovskite solar cell research, and transition metal iodides such as chromium and technetium iodides; the registry aliases also include astatine monoiodide, an interhalogen, and aluminium(II) iodide, whose existence as a stable compound could not be verified. Iodide deficiency causes goitre and developmental harm, while excess intake can also affect the thyroid, and potassium iodide tablets should be taken only when authorities advise.
What it is for: Chemistry, nutrition, medicine and materials.
It can be explain chemistry and examples; relay iodised salt and thyroid uses; relay radiation emergency guidance; describe named compounds.
Distinguishing features
Iodine in -1 state
Thyroid relevance
Ionic and covalent forms
Emergency medicine role
What it looks like
Mostly white or colourless salts; lead iodide is bright yellow.
Physical character
iodide ion charge: -1 note
Universal salt iodisation: recommended by WHO and UNICEF note - from 1993
lead iodide colour: yellow note
How it is recognised
Compound or ion of iodine
Lithium iodide, astatine monoiodide, aluminium(II) iodide, lead(II) iodide, chromium(III) iodide, technetium(III) iodide
Iodine is the element; iodates contain IO3 groups; organoiodine compounds have carbon-iodine bonds; chlorides contain chlorine

- Should potassium iodide be linked as a separate entry?
- How should radiation emergency guidance be linked by country?
