Francium is a radioactive, very rare, natural chemical element.
Francium is a highly radioactive and rare alkali metal. It is a solid at room temperature, but due to its extreme radioactivity, it is typically stored in mineral oil to prevent reaction with moisture in the air. Francium also has a silvery-white appearance when freshly cut.
Not known today but probably francium don't burn.
Francium has not applications and the oxide cannot be prepared.
Francium is a metal.
Francium was named after France, the country it was dicovered in.
The chemistry of francium is not known; francium has properties similar to caesium.
We haven't sufficient francium for a measurement; also francium is autovaporized.
As francium is a chemical element, it is made up of protons, neutrons and electrons.
Francium is a radioacive chemical element; francium is natural but also may be prepared in laboratory.
The atomic number of francium is 87.
The chemistry of francium is not known but it is supposed that francium can react with the majority of nonmetals.
