Fluorine Displacing Chlorine from Sodium Chloride
F2 + 2NaCl → 2NaF + Cl2
Overview
Fluorine, the most reactive element, displaces chlorine from sodium chloride to form sodium fluoride and chlorine gas. Fluorine is so reactive that it can even displace oxygen from water. This reaction occurs violently and must be handled with extreme care due to fluorine's extreme toxicity and reactivity.

Everyday Example
Sodium fluoride produced from fluorine reactions is used in toothpaste and water fluoridation to prevent tooth decay.
Industrial Importance
Fluorine chemistry is critical for the nuclear industry (uranium enrichment uses UF6), Teflon production, and in the manufacture of fluorinated pharmaceuticals.
