Francium hasn't applications.
Caesium applications:
- drilling fluids
- atomic clocks
- centrifugation fluids
- electronics
- catalyst
- gamma emitter (Cs-137)
etc.

What is an element related to francium?

Francium is similar to cesium.


Is the atomic size of francium greater than that of cesium?

Yes, the atomic size of francium is greater than that of cesium. Francium is located below cesium in the same group on the periodic table, so as you move down the group, atomic size generally increases.


Would francium combine with water more or less readily than cesium?

Francium would combine with water more readily than cesium. Francium is the most reactive alkali metal due to its position in the periodic table, so it would react more violently with water compared to cesium.


Why is francim more reactive than cesium?

Because the atom of francium is a whole row down from cesium. You see more YouTube videos of cesium in water because francium is highly radioactive, so it would be very hard to obtain a sample of francium to throw into water.


What is the second most reactive metal?

The 2nd most reactive is Cesium after Francium. If you disregard Francium because it is radioactive, then it would be Rubidium after Cesium.


Which element has the smallest atomic radius rubidium cesium and francium?

Francium has the largest atomic radius among rubidium, cesium, and francium, as atomic radius generally increases down a group in the periodic table.


Is most reactive which alkali metal?

Francium.


Which are most highly reactive compoudns?

radium francium and cesium


Why isn't francium the most electropositive element?

Although francium is very electropositive, cesium is typically considered more electropositive. This is because francium is rare and highly radioactive, making it difficult to study and utilize for practical purposes. Additionally, the large size of the francium atom leads to some electron shielding, decreasing its electropositivity compared to smaller atoms like cesium.


What atom is more reactive francium or cesium?

Francium is more reactive than cesium. This is due to francium's position in the periodic table, where elements at the bottom of a group tend to be more reactive than those at the top. Francium is the most reactive metal because of its large atomic size and low ionization energy.


What are two most reactive elements in the alkali group?

Francium and cesium


Francium wouls combine with water more or less readily than cesium?

Probable francium would react more violent.
