Reactivity of francium with air
So far as I understand, nobody has actually ever assembled enough francium in one location to recognize for particular its appearance. It is more than likely a really soft, easily reduced, solid steel, perhaps even a liquid at room temperature. A fresh francium surface would certainly soon tarnish because of reactivity via oxygen and moisture from the air. Were francium ever to be melted in air, the outcome is meant to be francium superoxide, FrO2.

Reactivity of francium via water
Francium is incredibly scarce and expensive. It is ummost likely that anyone has actually ever before reacted the steel via water. However before, provided that all the other Group 1 elements react to develop colourless solutions of the hydroxide and also hydrogen gas (H2), it would be stselection were francium not to perform the very same. The resulting solution would certainly be standard bereason of the dissolved hydroxide. The reaction would more than likely sbe quicker than that of caesium - in other words dangerously quick.
2Fr(s) + 2H2O(l) → 2FrOH(aq) + H2
Reactivity of francium with the halogens
So much as I know, nobody has ever before assembled enough francium in one location to bring out its reactions through halogens. However one can predict that francium metal would certainly react strongly with all the halogens to form francium halides. So, it would reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to create respectively francium(I) bromide, FrF, francium(I) chloride, FrCl, francium(I) bromide, FrBr, and also francium(I) iodide, FrI.
2Fr(s) + F2(g) → FrF(s)
2Fr(s) + Cl2(g) → FrCl(s)
2Fr(s) + Br2(g) → FrBr(s)
2Fr(s) + I2(g) → FrI(s)
Reaction of francium through acids
I"m not sure this reaction has actually ever been done, but one would certainly predict that francium steel will disresolve extremely readily in dilute sulphuric acid to form options containing the aquated Fr(I) ion along with hydrogen gas, H2.

Reaction of francium via bases
Francium is incredibly scarce and expensive. It is umlikely that anyone has ever before reacted the steel via water. However, offered that all the other Group 1 aspects react to create colourless fundamental services of the hydroxide and also hydrogen gas (H2), it would be stvariety were francium not to execute the same. The reaction would certainly proceed even as soon as the solution becomes fundamental. The resulting solution would be standard bereason of the dissolved hydroxide. The reaction would probably sbe much faster than that of caesium - in other words dangerously quick.
