Answer :
Lithium will react more intensively with water to form hydrogen gas.
The only alkaline earth metal that does not react with water is beryllium (Be). Its small size and high ionization energy compared to other elements in the group are the reason for this.
Six chemical elements from group 2 of the periodic table make up the alkaline earth metals. They are boron (R), barium (Ba), calcium (Ca), strontium (Sr), magnesium (Mg), beryllium (Be) and radium (Ra). The elements share many properties, including being shiny, silvery-white, moderately reactive metals at standard pressure and temperature. In terms of structure, they share (along with helium) the entire outermost s-orbital; This orbital has its full complement of two electrons, which the alkaline earth metals quickly lose to form cations with a +2 charge and +2 oxidation state, meaning it is completely complete.
