Reaction the francium with air
So much as ns know, no one has ever assembled enough francium in one place to recognize for details its appearance. It is most likely a an extremely soft, quickly cut, hard metal, perhaps even a fluid at room temperature. A fresh francium surface would shortly tarnish since of reaction v oxygen and moisture indigenous the air. To be francium ever before to be burned in air, the an outcome is meant to be francium superoxide, FrO2.

Reaction that francium v water
Francium is an extremely scarce and also expensive. That is umlikely that anyone has ever reacted the steel with water. However, offered that every the other group 1 aspects react to type colourless remedies of the hydroxide and hydrogen gas (H2), it would certainly be strange were francium no to execute the same. The resulting solution would be simple because the the dissolved hydroxide. The reaction would most likely sbe faster than that of caesium - in other words dangerously quick.
2Fr(s) + 2H2O(l) → 2FrOH(aq) + H2
Reaction that francium v the halogens
So much as ns know, nobody has ever assembled sufficient francium in one place to bring out its reactions through halogens. Yet one deserve to predict that francium steel would reaction vigorously v all the halogens to kind francium halides. So, it would reacts v fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively francium(I) bromide, FrF, francium(I) chloride, FrCl, francium(I) bromide, FrBr, and 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 ever before been done, however one would predict that francium metal will dissolve very readily in dilute sulphuric acid to kind solutions containing the aquated Fr(I) ion together with hydrogen gas, H2.

2Fr(s) + H2SO4(aq) → 2Fr+(aq) + SO42-(aq) + H2(g)
Reaction that francium v bases
Francium is really scarce and expensive. The is umlikely that anyone has ever before reacted the metal with water. However, given that all the other group 1 aspects react to kind colourless simple solutions of the hydroxide and hydrogen gas (H2), it would certainly be strange were francium no to perform the same. The reaction would continue even when the solution becomes basic. The resulting systems would be basic because that the dissolved hydroxide. The reaction would probably sbe faster than the of caesium - in various other words dangerously quick.
