Question

I would like a list of random, interesting facts about Francium.

Please give a minimum of 5 facts, and don't state the obvious, such as a boiling point.

Answer 1

It has the highest equivalent weight of all elements.
Prior to its discovery, it was simply referred to as eka-caesium.
The most stable isotope, Fr-223, has the longest half-life at 21.8 minutes.
Francium has thirty-four known isotopes, with only two of them occurring in nature.
It is the most unstable of all elements that occur naturally.
Hope this helps.
