Francium chloride is a radioactive chemical compound with the formula FrCl. It is a salt predicted to be a white solid and is soluble in water. Its properties resemble caesium chloride.[1]
Production
It is produced by the reaction of hydrochloric acid with francium metal:[1]
- 2Fr + 2HCl → 2FrCl + H2
It is also expected to be produced by the violent reaction of francium and chlorine gas.[2]
Decay
Francium is highly radioactive. Its half life is only 22 minutes and it decays into elements like astatine, radon, or radium[3] and thus decays into AtCl, RaCl2, or RnCl2.
Uses
It is used mainly for scientific research and can also be used to diagnose cancerous growths although the high cost of francium makes this unfit for general use.[4]
