Fluorine (Latin: fluere, meaning "to flow") is one of the chemical elements. Fluorine has atomic number 9, and symbol F. Fluorine is poisonous gas,(toxic), and highly corrosive. It has a yellow-green tint to it. This element has high electronegativity and extremely reactive with other chemicals. It reacts with all organic and inorganic substances. When it reacts with water, it is very dangerous. Fluorine is very useful, so it is used for many things in our daily lives. For example, the toothpaste that we use everyday contains fluorine. | Fluorine (Latin: fluere, meaning "to flow") is one of the chemical elements. Fluorine has atomic number 9, and symbol F.

Because of the special properties of Fluorine, it can be used for many purposes. Fluorine is excellent against the tooth decay. Fluoride covers teeth with thin layers, so it protects from forming cavities. In addition, many nations add Fluorine into the city water for disinfection. Fluorine is also used in the manufacture of Freon, which is used in the refrigerator. Unfortunately, freon fills the air with pollutants, and eats the Ozone layer. | Because of the special properties of Fluorine, it can be used for many purposes.

Although fluorine (F) has multiple isotopes, only one of these isotopes is stable; as such, it is considered a monoisotopic element. | Although fluorine (F) has multiple isotopes, only one of these isotopes is stable; as such, it is considered a monoisotopic element. | ||
