“Fluorine (F)”  [Atomic Number: 9] 

Fluorine

  The trace element Fluorine (F) is a reactive nonmetal element, and the lightest halogen chemical element with atomic number 9, represented by the symbol F, found as the thirteenth most abundant element in the earth's crust yet not naturally found as a free element on earth.
In elemental science, Fluorine (F), is a p-block element, located at the group 17 (aka fluorine group), period 2 of the periodic table of elements.
  Chemically, a diatomic gas Fluorine (symbol F) is one of the strongest oxidizing agents known, similar to, and even more reactive and dangerous than, it's halogen's cousin elemental chlorine (Cl).

Fluorine, in its elemental form, is a pale yellow, highly toxic and corrosive gas which uniquely affects the properties of organic molecules, through strong polar interactions due to the atom's high electronegativity and small size.
  Examples of fluorine (F) related topics include:

• fluorine isotopes
  • fluorine radioisotopes
• fluorination
• fluorine compounds (fluorinated compounds)
• fluorides

“Fluorine Isotopes”  

  In chemistry, Fluorine Isotopes are isotopes of stable fluorine atoms that have the same atomic number as elemental fluorine (F), but differ in atomic weight.
  
  The fluorine isotopes include:

• fluorine radioisotopes

“Fluorine Radioisotopes”  

Fluorine Radioisotope

  In chemistry, Fluorine Radioisotopes are unstable isotopes of the element fluorine (F) that decay or disintegrate emitting radiation. **

“Fluorination”  

  In chemistry, Fluorination is a halogenation chemical reaction involving the covalent attachment of one or more of a halogen atoms of the element fluorine (F) to a compound or material. **

“Fluorides”  

Fluoride

  In inorganic chemistry, Fluorides, as ionic anions, are hydrofluoric acid (HF) salts, in which the fluoride atom is in the -1 oxidation state.

The anion Fluoride, molecular formula F with a net charge of -1, is a reduced form of the element fluorine (F), when as an ion and when bonded to another element. Fluoride as a halide anion has a monovalent ion (-1 charge).

Fluorine to Fluoride

  A fluorine (F) atom becomes a Fluoride anion, F−, by gaining one electron without an increase number of protons.

Fluoride Competes with essential Halogen Nutrients

In our body, Fluoride competes with essential nutrient Halogens, because it is also a member of the halogen family.

Essential Nutrient Halogens include iodine, chlorine and bromine. Fluoride competes with these elements in the physiological function of certain organs, such as iodine-dependent breast and thyroid tissue.
