- francium is extremely radioactive- the total quantity of francium on the Earth is approx. 30 g- the chemical and physical properties of francium are only estimated, not measured
1. Francium is the most reactive metal.2. The estimated melting point is 30 oC.
Lithium, sodium potassium, caesium, rubidium and francium are all alkali metals; consequently they share many chemical and physical properties.
Francium bromide is not known.
Francium chloride is a radioactive chemical compound with the formula FrCl. It is predicted to be a white solid and is soluble in water. Its properties resemble caesium chloride. It is produced by the reaction of hydrochloric acid with francium metal. Source: Wikipedia
