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.
Potassium is more reactive in water compared to cesium. When potassium reacts with water, it produces hydrogen gas and heat at a faster rate than when cesium reacts with water.
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.
In reaction with water and oxygen Fr is more reactive than Cs
because it is less stable
I would expect cesium, element 55, to be more reactive than potassium. This is because cesium is further down the alkali metal group in the periodic table, making it more eager to lose an electron compared to potassium.
AnswerDespite the fact that you could look it up that cesium is indeed more reactive than potassium, you could also take into account the periodic trends. One of these trends is that metals tend to be more reactive as you proceed down a group/family and as you move to the left of the table. Since both cesium and sodium are members of the alkali metals, cesium should be more reactive of the two.
Francium is more metallic than cesium. It is an alkali metal located below cesium in the periodic table and is the most reactive metal known.
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.
Cesium is more reactive than barium. Cesium is located lower down in Group 1 of the periodic table, making it more reactive than barium, which is further up the group. Cesium readily reacts with air and water, while barium is less reactive in comparison.
The high reactivity of cesium comes from its tendency to give up the one electron in its outermost shell and become a cesium 1+ ion, which is more stable. In cesium chloride, the cesium is already in its stable ionic form.
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.
