Let an agent explain fluorides, relay chemistry, examples, dental uses, toxicity and fluoridation debates from chemistry, WHO and public health sources with positions attributed, route poisoning and hydrofluoric acid exposure to emergency services, describe the named compounds, and distinguish fluorides from elemental fluorine, fluorocarbons and PFAS, 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 fluorides, relay chemistry, examples, dental uses, toxicity and fluoridation debates from chemistry, WHO and public health sources with positions attributed, route poisoning and hydrofluoric acid exposure to emergency services, describe the named compounds, and distinguish fluorides from elemental fluorine, fluorocarbons and PFAS, and chlorides.

A compound containing fluorine in the minus one oxidation state bonded to other elements, or the fluoride ion itself, including ionic salts such as calcium fluoride, the mineral fluorite, sodium fluoride, magnesium fluoride used in optics, ammonium fluoride and caesium fluoride, and covalent molecular fluorides such as sulfur and uranium hexafluoride, used in uranium enrichment, and pertechnetyl fluoride; fluoride in toothpaste and community water fluoridation reduces tooth decay, while excessive intake causes dental and skeletal fluorosis, and the levels and risks of fluoridation are debated, with positions attributed. Hydrofluoric acid and some fluorides are highly toxic, and exposure needs emergency services or a poison centre.

What it is for: Chemistry, industry and dental health.

It can be explain chemistry and examples; relay dental uses and fluorosis; present fluoridation debates with attribution; route poisoning emergencies.

Distinguishing features

Fluorine in -1 state

Ionic and covalent forms

Dental benefit

Toxicity at high doses

What it looks like

Varied: colourless crystals, white powders, the purple or green mineral fluorite, and gases such as sulfur hexafluoride.

Physical character

WHO drinking water guideline: 1.5 mg per litre - fluoride

fluoridation began: 1945 year - Grand Rapids, Michigan

fluoride ion charge: -1 note

How it is recognised

Compound or ion of fluorine

Hexafluoride, magnesium fluoride, calcium fluoride, ammonium fluoride, pertechnetyl fluoride, caesium fluoride

Elemental fluorine is a reactive gas; fluorocarbons and PFAS have carbon-fluorine bonds; chlorides contain chlorine
