Answer:

We can't?

Explanation:

Of course francium metal reacts with water with ALACRITY:

#Fr(s) + H_2O(l) rarr Fr^+ + HO^(-) + 1/2H_2(g)uarr#

#""^87Fr# is an unstable isotope, short-lived and highly expensive, and would be only available in milligram quantitities. Its reaction with water would be rapid and quantitative.

Answer:

You would never be able to gather enough together to form a "piece" of Francium, let alone put it in water.....

Explanation:

Francium is an extremely unstable element. It occurs as a number of isotopes, but even the most stable one (#Fr_223#) has a half life of about 20 minutes!

#Fr_223# can be found in nature in certain radioactive ores, such as uranium ore. Within these, #Fr_223# is continually formed by radioactive decay and subsequently decays itself.

If you take the entire earth's crust, the most #Fr_223# you will ever find in existence at any one time is less than 50 g! So its pretty difficult to gather enough together to drop it into water!
