Web22 feb. 2024 · When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. WebFluorine is a pale yellow gas with a pungent odor. It is commonly shipped as a cryogenic liquid. It is toxic by inhalation and skin absorption. Contact with skin in lower than lethal concentrations causes chemical burns. It reacts with water to form hydrofluoric acid and oxygen. It is corrosive to most common materials.
