Francium can be obtained by this reaction:
Au-197 + O-18 = Fr-210 + 5 n
Francium is a highly radioactive element, so it is not naturally found in significant quantities in any food sources. It is produced in very small amounts as a decay product of uranium and thorium. Due to its extreme rarity and radioactivity, it is not present in any food sources in substantial quantities for consumption.
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.
Francium is not a commercial product.
Francium is not a commercial product.
Francium has not a smell.
