What is the difference between a fluoride ion and a fluorine atom

Fluoride either refers to the fluorine ion or to a compound that contains the element fluorine. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile.

In reality, they are either deliberately lying about fluoride toxicity or have incorrectly and irrationally assumed that just because fluorine gas and fluoride are not the same thing, fluoride must be more or less harmless.

They also claim that fluoride is biologically similar to iodine merely because they are both halogens, which is equally silly. Bromine is another halogen, and is also neither a nutrient nor biologically similar to iodine. The biochemistry of the halogen chlorine, including its ionic form, chloride, is also very different to the other halogens.

You can go through the rest of the naturally occurring chemical elements, and the groups they belong to, and the story is the same. Biochemistry relies on a knowledge of chemistry, but it is studied separately from Chemistry for a reason. The former term was actually preferred prior to , or thereabouts.

I encountered one fluoridationist who admitted not having read Fluorine Intoxication by Europe -based researcher Kaj Roholm , but who still insisted the book is not about fluoride. For example, the ionic compound potassium iodide KI is commonly referred to as an iodine supplement when used for that purpose. It is also important that those of us who are pro-choice on taking fluoride get our facts straight, even if the argument against forced-fluoridation does not depend on those particular facts.

Fluorine and consequently its ionic form, fluoride is a non-metal, not a heavy metal or any other kind of metal. Metals form positive ions called cations whereas fluorine only forms the negative ion i. The fluoridation chemicals which are used for forced-fluoridation are industrial grade, and come with contaminants which include heavy metals, but the fluoride itself is not metallic. Additionally, it should be understood that although some ionic fluoride compounds are more hazardous than others, due to differences in bioavailability and possibly other reasons in some cases e.

For example, active volcanoes give off large quantities of hydrogen fluoride HF gas, which is highly bioavailable and highly toxic. When you eat or drink, at least some of the fluoride which is ingested forms HF in your stomach acid, regardless of whether it came from an artificial or natural source. The study of what happens to chemicals taken into the body is known as pharmacokinetics. The physics or chemistry of fluorine and fluoride Fluoride chemical symbol F — is the ionic form of fluorine F.

Fluoride or fluorine in tap water Tap water almost invariably contains many different types of anions and cations in solution i. Why the confusion? Why it matters So why does this matter?
