![]() ![]() ![]() So, it would reacts with fluorine, F 2, chlorine, Cl 2, bromine, I 2, and iodine, I 2, to form respectively francium(I) bromide, FrF, francium(I) chloride, FrCl, francium(I) bromide, FrBr, and francium(I) iodide, FrI.ĢFr(s) + I 2(g) → FrI(s) Reaction of francium with acids However one can predict that francium metal would react vigorously with all the halogens to form francium halides. So far as I know, nobody has ever assembled enough francium in one place to carry out its reactions with halogens. The reaction would probably sbe faster than that of caesium - in other words dangerously quick.ĢFr(s) + 2H 2O(l) → 2FrOH(aq) + H 2 Reaction of francium with the halogens The resulting solution would be basic because of the dissolved hydroxide. However, given that all the other Group 1 elements react to form colourless solutions of the hydroxide and hydrogen gas (H 2), it would be strange were francium not to do the same. It is umlikely that anyone has ever reacted the metal with water. Were francium ever to be burned in air, the result is expected to be francium superoxide, FrO 2.įr(s) + O 2(g) → FrO 2(s) Reaction of francium with waterįrancium is very scarce and expensive. A fresh francium surface would soon tarnish because of reaction with oxygen and moisture from the air. ![]() It is probably a very soft, easily cut, solid metal, perhaps even a liquid at room temperature. So far as I know, nobody has ever assembled enough francium in one place to know for certain its appearance. ![]()
