The formula for the fluoride anion is F−.
Understanding the Fluoride Anion (F−)
The fluoride anion, represented by the chemical formula F−, is the ionic form of the element fluorine. It forms when a neutral fluorine atom (F) gains one electron to achieve a stable electron configuration, resulting in a net negative charge.
Key Characteristics of Fluoride (F−)
As the simplest inorganic, monatomic anion of fluorine, the fluoride ion possesses distinct characteristics:
- Monatomic: It consists of a single atom.
- Inorganic: It is a chemical compound not derived from living organisms, typically without carbon-hydrogen bonds.
- Anion: It is an ion with a net negative electrical charge.
- Basic Properties: The fluoride ion exhibits basic properties, meaning it can accept a proton (H+) in solution.
