REACTIONS OF THE GROUP 1 ELEMENTS WITH WATER " Periodic Table" All the alkali metals react vigorously with cold water. In each reaction, hydrogen gases given off and the metal hydroxide is produced. The speed and violence of the reaction increases as you go down the group. This shows that the reactivity of the alkali metals increases as you go down Group 1. How does Sodium React with Water? Sodium melts and forms a floating ball of metal which fizzes .as it moves over the surface of the water giving off hydrogen gas How does Potassium React with Water? Potassium is the most reactive. It melts, reacts vigorously and burns with a lilac flame as it gives off hydrogen gas. Potassium is dangerous and can explode when it comes into contact with water. مشروع الطالب الالكتروني
