Francium is a highly radioactive metal that decays into astatine, radium, and radon.
From the en.wikipedia.org
In 1939 she isolated francium, the 87th element in the periodic table.

Initially, about 1000 francium atoms were trapped in the experiment.
From the en.wikipedia.org
This was the very first time that anyone had ever seen francium.
From the en.wikipedia.org
The density of francium is an estimation partially based on periodic trends rather than observations.
From the en.wikipedia.org
Soviet chemist D. K. Dobroserdov was the first scientist to claim to have found eka-caesium, or francium.
From the en.wikipedia.org
This is unusual as periodic trends would predict ununennium to be even more reactive than caesium and francium.
From the en.wikipedia.org
Because radioactive elements give off heat, francium would almost certainly be a liquid if enough were to be produced.
