Elemental fluorine (F₂) is a hazardous, pale yellow gas that is rarely found in pure form due to its strong reactivity. It has the highest electronegative and reactive properties of any element on the periodic table. Fluorine rapidly interacts with practically all other elements, including noble gases, to generate fluorides. It is utilised in a variety of industrial applications, including the synthesis of fluorocarbons for use as refrigerants and propellants, as well as the creation of other compounds. Because of its hazardous nature, elemental fluorine must be handled and stored using specialised equipment and methods.
