Not known today but probably francium don't burn.
Francium has not applications and the oxide cannot be prepared.
Francium is an extremely reactive element and would react violently with cold water, releasing a large amount of energy in the process. This would result in a rapid explosion due to the formation of hydrogen gas and the release of significant heat energy. Francium is so rare and radioactive that there are no known instances of it reacting with water.
This property was not measured on francium.
Yes, francium is a solid alkali metal.
I suppose that francium cannot be stored: the half life is short.

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.
Francium is a soft, highly reactive metal. It is the most unstable of all the naturally occurring elements due to its large atomic size and low electronegativity. It readily reacts with other elements, so it is typically stored in inert gas to prevent this.

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.
