Hygroscopic. Reacts readily and exothermically with water to form a solution of corrosive
Does barium react rapidly with water?
This is the reason why barium reacts more rapidly with cold water than magnesium. So option A, is the correct answer. Note: Larger on going down the group the ionization energy decreases and hence greater is the ease in losing electrons for an atom.
Does barium explode in water?
Barium reacts violently with WATER and MOIST AIR to generate flammable and explosive Hydrogen gas. Mixtures of finely divided Barium and HALOGENATED HYDROCARBONS (such as TRICHLOROETHYLENE and CARBON TETRACHLORIDE) are explosive.
