Lithium floats on the surface of water, where it begins to fizz as it slowly releases hydrogen and eventually dissolves. Copyright © 2020 Multiply Media, LLC. 13446-72-5. Francium is below cesium on the table and would react more readily and violently. Rubidium reacts very violently with water to make hydrogen and rubidium hydroxide, a strong corrosive base. ". The reaction is very exothermic. 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. Rubidium is very reactive. It has a relatively low melting point of 39°C. rubidium + water ==> rubidium hydroxide + hydrogen; 2Rb(s) + 2H 2 O(l) ==> 2RbOH(aq) + H 2(g) Cesium is much too dangerous a metal to add to acids because of its high reactivity. ACMC-20ajse ACMC-20ajse Rubidium is an alkali metal in the same group (Group I) as sodium and as one goes down the group the ionization energy decreases (See below Table 1 column 3). The reaction is so fast that if the reaction is carried out in a glass vessel, the glass container may well shatter.
