It is not possible.
The francium hydride should be FrH.
The chemistry of francium is not known but francium is considered the most reactive metal.
I'd predict that francium would combine less readily than cesium.
Francium is most reactive - the Pauling electronegativity is calculated to be 0,7.
Probable francium would react more violent.
Very probable the reaction of francium should be more violent.
Probable a hydride is formed but this reaction is impossible to be realized today.
It is supposed that francium react with water more easy than any other element.
Supposing you mean cesium, I would say no. You see, when francium and water are mixed they react much more violently than cesium in water, causing a greater explosion. Therefore, cesium would combine more rapidly.
Francium was named after France, the country it was dicovered in.
The Group 1 elements have a specific family name - alkali metals. All the alkali metals are silvery solids with low densities and low melting points. These elements increase in their reactivity, or tendency to combine with other substances, as you more from top to bottom on the periodic table.Alkali metals are found in many items. Lithium batteries are used in cameras. Sodium chloride is common table sat. Sodium and potassium, dietary requirements, are found in small quantities in potatoes and bananas.I'd predict that francium would combine less readily than cesium.______________Well, actually, Francium is a radioactive element, and it's a pretty unstable one at that; Alkali metals tend to explode somewhat when placed in water.Cesium then will explode in water, and Francium will, undoubtedly, undergo radioactive decay into Radium, and when that's placed into water...To answer the question :Francium will most definitely combine readily (if not violently) with water more than Cesium.
Not known today but probably francium don't burn.
