While going down the second group, the reactivity of the alkaline eart

1.	While going down the second group, the reactivity of the alkaline earth metals increases.
Answer» SOLUTION :The reaction of alkaline earth metal with water is `M+2H_(2)OrarrM(OH)+H_(2).` While going down the SECOND group as `Be rarrMgrarrCararrSr rarrBa,` the GRADATION in this chemical property of the alkaline earth metals is seen. While going down the second group the REACTIVITY of the alkaline earth metals goes on increasing thereby the ease with which this reaction takes place ALSO goes on increasing. Thus, Beryllium (Be) does not react with water. Mg (Magnesium) reacts with steam. Whereas calcium (Ca), strontium (Sr) and barium (Ba) reacts with water at room temperature with increasing rates.
