WebIn chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides. All the alkaline earth metals except beryllium also react with water to form strongly alkaline hydroxides which should be handled with great care. The heavier alkaline earth metals react more vigorously than the lighter ones. Weblithium + water Cesium is another member of the alkali metal family. Following the reaction trend shown in the videos, cesium is most likely O of similar reactivity with water to sodium. less reactive with water than potassium.
