Radium fluoride is an inorganic compound with a chemical formula of RaF2. This salt, like all radium compounds, is highly radioactive. It can be coprecipitated with lanthanide fluorides.[2] Radium fluoride has the same crystal form as calcium fluoride (fluorite).[citation needed] However, calculations suggest that radium fluoride vapor consists of RaF2 molecules, with a bond angle of 118°, due to substantial covalent interaction within the molecule.[3]
