Francium is lower down group 1 than Caesium so should be more reactive.?

Question

What would happen if you put Francium in water?
Would it explode? The Cs reaction is pretty violent.

2Fr + 2H2O >>>>>2Fr OH + H2 ????????

GTB..why would it kick out less energy than Caesium..it should be more reactive.

Cheek ..it seems that it is ,like mercury a liquid at room temperature...now I did not know that!!

Kaiser Bill..at the time of writing I was not sure what state Francium was..so rather than get it wrong I omitted them...sorry Sir,..200 lines for me.

Answer 1

reading about the element in some science tech sites, they say that it is not very stable with a half life of 21 minutes before decay and can only be studied as a trace element as it doesn't last long.

I figure that something that is reactive the the Oxygen in water will also be reactive to air if it is in the same league as Caesium but more reactive.

I have seen some metals in a Physics demonstration on metals that oxidise in air that rapid that to cut them will show bright shiny surface but quickly tarnishes through oxidising in air in a matter of seconds.

Answer 2

Francium IS more reactive than Caesium. It would not 'kick out' less of a reaction than Caesium. It would cause an explosion (of Hydrogen).

Also, where are the chemical state indicators in your equation? See me after class!

Answer 3

It would be violently reactive and the equation you show is correct.

I suspect it kicks out less energy than Cs but still all alkali metals are very potent.

Answer 4

I believe it should lead to a violent explosion, but I haven't done chemistry for 20 years and may be wrong about it.

Answer 5

React violently and most probably shatter the glass trough.
Your equation is correct.
