Francium was discovered by Marguerite Perey in 1939.
Francium is a highly reactive metal that is extremely rare and unstable. It is also radioactive, which makes it dangerous to handle. Due to these properties, francium is not commonly used in everyday applications.
Not known today but probably francium don't burn.
Francium gives away electrons very easily due to its location in the alkali metal group, which makes its outer electron very loosely bound. This makes Francium highly reactive and likely to form ions by losing its single valence electron.
Sodium and francium are both highly reactive metals due to their low ionization energy and strong desire to lose an electron to achieve a stable electron configuration. Francium is more reactive than sodium because it has a larger atomic radius and lower ionization energy, making it easier for francium to lose its outermost electron. This increased reactivity makes francium the most reactive metal among all the elements.
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.
