  3. 1.Chlorine(Cl) Potassium(k) rubidium (Rb) Cesium(Cs) all of these with water (H20)

    2.Lithium, sodium,Potassium,Rubidium,Cesium

    3Yes.

    4.No
    5.Some of them burst instantly , some other just react a little , they are create heat , hydrogen gas.

    6.I dont know

    7.Group IA
