It might have slipped your attention that fluorine is added to tap water as sodium hexafluorosilicate of fluorosilicic acid. Halothoane and Sevoflurane both are halogenated fluorocarbons, HFCs.
It is normally accomplished by adding one of three compounds to the water: sodium fluoride, fluorosilicic acid, or sodium fluorosilicate.
The expression "compound" therefore is more adequate than talking about "fluorine atoms" or ions.
That semantic topic however is not the core of the discussion.
You pretty much hit bottom.
That depends from the point of view.
