francium is found in thorium and uranium ores in the earth's crust obtained by the decay of actinium
Francium exists in uranium and thorium ores.
Francium can be detected only by nuclear spectrometry.
The existence of francium in cosmos was not proved.
Francium exist in infinitesimal traces in thorium and uranium ores.
bombs cannot be built with francium.
If it would be prepared the chemical formula of francium hydroxide is FrOH.
The predictions are based on the supposition that francium is similar to caesium.
If francium could be obtained in large quantities would have a definite volume.
Francium is a liquid at 50 0C.
Francium would react with water by this equation: 2Fr + 2H2O -->2FrOH + H2 The products here are francium hydroxide and hydrogen gas. However, it would be impossible to gather enough francium to demonstrate this reaction.
The chemical reactions of francium are probably similar to the reactions of caesium or rubidium.
Francium is very rare and would be correspondingly expensive if you were able to purchase any, which you probably aren't.
