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.
At 50 degrees Celsius, francium would be in a solid state. Francium is a metal that has a melting point of 27 degrees Celsius. At temperatures lower than its melting point, francium would exist as a solid.
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.
The compound formed between sodium and francium would be NaFr, with sodium as the cation and francium as the anion. This compound would have a 1:1 ratio of sodium to francium ions.
Francium is an extremely rare and highly radioactive element, making it difficult to find in nature. Due to its extreme rarity and radioactivity, francium is not commonly found in compounds. However, some theoretical compounds containing francium may include francium fluoride (FrF) or francium hydroxide (FrOH), although these would be highly unstable and challenging to create and study in a laboratory setting.
If francium could be obtained in large quantities would have a definite volume.
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.
Mixing sulfuric acid with francium would result in a vigorous chemical reaction. Francium is a highly reactive alkali metal that would react violently with the sulfuric acid, potentially causing an explosion and generating hydrogen gas. This reaction would also produce francium sulfate and release a considerable amount of heat.
