▸ The reading
interpretive · artFluorine is the most electronegative element on the table, and it collected casualties: several chemists died attempting the isolation before Moissan succeeded in 1886. Tamed, it strengthens tooth enamel from a tube of toothpaste and lines the non-stick pan. The fiercest appetite in chemistry, domesticated — that inversion is the whole reading.

▸ Discovery
Henri Moissan — isolated via electrolysis of HF; the long hunt killed multiple chemists · France · 1886
▸ Stellar origin
Uncertain — AGB stars, massive stars, supernovaeFluorine is rare in the cosmos and its origin is still debated — AGB stars are the only observationally confirmed source; rotating massive stars, Wolf-Rayet winds and neutrino spallation in core-collapse supernovae (a neutrino strips a proton off neon) are also proposed.
▸ Reactivity
Most electronegative element on the tableWill steal electrons from almost anything, including noble gases (XeF₆) and water (gives O₂ + HF + heat). Glass and even some metals burn in F₂.
▸ Applications
- Fluoride in toothpaste / drinking water
- Teflon (PTFE) — non-stick coatings
- Refrigerants and fluoropolymers
- Uranium enrichment (UF₆)
▸ Curiosity
Several chemists died trying to isolate this element before Moissan finally succeeded.
