Fluorine (chemical symbol F) is a non-metallic chemical element that is part of the halogen family. This element is in the gaseous state at normal temperature and pressure. It is the lightest of all halogens and has highly reactive properties.

Fluorine is a white solid at room temperature and has a molar mass of 18.9984 g/mol. It burns with a flickering blue light when exposed to flame. The melting temperature of Fluorine is -219.62°C and its boiling temperature is -188.14°C.

Fluoride has many properties and uses. It is one of the strongest oxidants because it can easily bond with a large number of other chemical elements such as Oxygen, Sodium, Calcium and Magnesium. Fluorine is a halogen whose compounds are highly flammable. Fluorine compounds are used in many industrial and medical applications. It is used in chemicals, pharmaceuticals, building materials, chlorofluorocarbon and more.

In addition, fluoride is also useful for human health. It is found in dental products such as artificial teeth and dental varnishes. It is also added to oral hygiene products, such as toothpaste, to help prevent tooth decay.
