For example, francium chloride would be produced by the reaction of francium and chlorine. Francium chloride has been studied as a pathway to separate francium from other elements, by using the high vapour pressure of the compound, although francium fluoride would have a higher vapour pressure. [3]
Francium-223 also has a shorter half-life than the longest-lived isotope of each synthetic element up to and including element 105, dubnium. [8] Francium is an alkali metal whose chemical properties mostly resemble those of caesium. [8] A heavy element with a single valence electron, [9] it has the highest equivalent weight of any element. [8]
Occurrence, nature - I think a reaction scheme here would help like used in Compounds section. I see two problems with this. One is that doing this would be redundant. The other is that francium doesn't exist naturally as a compound. As such, reactions and compounds have no place in the natural occurence section.
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. It is a salt predicted to be a white solid and is soluble in water.

The alkali metals can also react analogously with the heavier chalcogens (sulfur, selenium, tellurium, and polonium), and all the alkali metal chalcogenides are known (with the exception of francium's). Reaction with an excess of the chalcogen can similarly result in lower chalcogenides, with chalcogen ions containing chains of the chalcogen ...
