In reaction with water and oxygen Fr is more reactive than Cs
The 2nd most reactive is Cesium after Francium. If you disregard Francium because it is radioactive, then it would be Rubidium after Cesium.
Francium.
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.
Francium is more reactive than cesium. It is the most reactive metal due to its position in the periodic table - the farther down and to the left an element is, the more reactive it tends to be.

Francium and cesium
Francium is more reactive than cesium as it is the most reactive metal in the alkali metal group. Its reactivity is due to its low ionization energy and high atomic size, making it highly reactive with other elements. However, due to its extreme rarity and radioactivity, francium is not often encountered in practical situations.
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.
the alkali metals are the most reactive... either cesium or francium would be the most reactive out of this group.
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.
Francium is the most reactive alkali metal due to its location at the bottom of the group and its low ionization energy. It reacts violently with water, air, and other elements. However, it is extremely rare and radioactive, making it difficult to study its reactivity in depth.
