if you mean pure barium as in barium metal then yes it is very reactive if you left a piece of it
out in the open air over night it would turn to a pile of white barium oxide and other various compounds
The most reactive element among cesium (Cs), barium (Ba), and lutetium (Lu) is cesium (Cs). Cesium is located at the far left of Period 6 in the periodic table and has a single valence electron, which makes it highly reactive.
Cesium (Cs) is the most reactive among cesium, barium, and lutetium because it is located at the far left of Period 6, making it the largest and having the lowest ionization energy. This means cesium readily loses an electron to form Cs+ ions, exhibiting high reactivity.
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.
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.
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.

No, it is less reactive.

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.

Cesium is more reactive. Down the group reactivity increases.
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.

In reaction with water and oxygen Fr is more reactive than Cs

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.
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.
