What does francium make?

Francium's most stable isotope, francium-223, has a half-life of about 22 minutes. It decays into radium-223 through beta decay or into astatine-219 through alpha decay. Due to the small amounts produced and its short half-life, there are currently no uses for francium outside of basic scientific research.

Besides, how does francium react with water?

Reaction of francium with water. Francium is very scarce and expensive. It is umlikely that anyone has ever reacted the metal with water. However, given that all the other Group 1 elements react to form colourless solutions of the hydroxide and hydrogen gas (H2), it would be strange were francium not to do the same.

How long does francium last for?

Francium is one of the most unstable of the naturally occurring elements: its longest-lived isotope, francium-223, has a half-life of only 22 minutes.

Why is francium so reactive in water?

Larger atoms = more reactive. So potassium is more reactive than lithium because the outer electron of a potassium atom is further from its nucleus than the outer electron of a lithium atom. Francium atoms, with 7 shells, are the largest atoms in Group 1. They are very reactive - now you know why.
