Cs 2 O 2 can be formed by oxidation of the metal with the required amount of oxygen, but other reactions of cesium with oxygen are much more complex. Cesium superoxide has a more reddish cast. But, due to rareness of francium, experiments may be not done to test its reactivity with water. Therefore, all group 1 metals should react with water. We see, reaction rate of group 1 metals with water increases when going down the group. The csium reaction in these successive crops diminished, until in the. If a metal sample has a large enough surface area, it can burn to form superoxides. Lithium, sodium, potassium, rubidium, caesium and francium belongs to alkali metals. These were rinsed with water, and successively re - crystallised from fresh. Plants and vegetation growing in or nearby contaminated soil may take up small amounts of Cs-137 from the soil. Cesium is difficult to handle because it reacts spontaneously in air. A small amount of lithium will float on water and burn. Cesium binds strongly to soil and concrete, but does not travel very far below the surface. You are most likely to need to know this in their reactions with water. Rubidium and caesium are both a bit denser than water, and so sink in water. Lithium, sodium and potassium are all less dense than water, and so float on water.

Therefore, the experiment which produces the most vigorous reaction with water is (C), cesium. Rubidium and water were taken together using various ways: running chemist method, dropping hammer method, dropping water method with Rb piece, dropping wate. Notice that caesium melts not far above a normal room temperature.
