The reaction is slower than that of caesium (immediately below rubidium in the periodic table), but faster than that of potassium (immediately above rubidium in the periodic table). Management. metals react with water by donating there electrons to the water, rubidium has more electron shells therefore has more electron sheilding therefore weaker nuclear attraction on the outer electron, this means the water can accept the electron more easier therefore why reacts for violently. Like other group 1 elements this metal reacts violently in water. Rubidium reacts very violently with water to make hydrogen and rubidium hydroxide, a strong corrosive base. If rubidium is burned in air, the result is mainly formation of dark brown rubidium superoxide, RbO2. It has high electropositive values and is ranked second among the stable alkali metal.
