F2
Fluorine gas · Molecular fluorine, Difluorine
Fluorine gas is a highly reactive, insulating diatomic molecule that serves as a potent chemical oxidant in industrial and laboratory synthesis.
About Fluorine gas
Fluorine gas is the diatomic form of the most electronegative element in the periodic table. As a wide-band-gap insulator, it exists as a pale yellow gas under standard conditions and is characterized by its extreme chemical reactivity, which stems from the relatively weak bond between its atoms.
Its thermodynamic stability on the convex hull underscores its role as a fundamental building block in inorganic chemistry. It is widely utilized in industrial processes that require aggressive fluorinating agents, particularly in the production of specialized materials and high-performance electronics.
Key Properties
Cross-validated computational properties for Fluorine gas, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
