As a strongly radioactive element francium is dangerous for humans beings.
These effects were not studied for francium but because francium is very radioactive it is harmful.
Being very radioactive francium is dangerous. Irradiation destroy body cells and cause cancers.
Francium was named after France, the country it was dicovered in.
Francium is very radioactive and very difficult to obtain; heating of francium due to the decay leads to instantaneous vaporization of francium.
Francium is not explosive.

Not known today but probably francium don't burn.
Francium has not applications and the oxide cannot be prepared.
Francium can form cations with the charge +1.
Francium is a metal.
Francium is a true chemical element, not an example.
We haven't sufficient francium for a measurement; also francium is autovaporized.
