REACTIONS OF THE GROUP 2 ELEMENTS WITH WATER This page looks at the reactions of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium - with water (or steam). It uses these reactions to explore the trend in reactivity in Group 2. The Facts Beryllium Beryllium has no reaction with water or steam even at red heat. Magnesium Magnesium burns in steam to produce magnesium oxide and hydrogen. Very clean magnesium has a very slight reaction with cold water. The reaction soon stops because the magnesium hydroxide formed is almost insoluble in water and forms a barrier on the magnesium preventing further reaction. Note: As a general rule, if a metal reacts with steam, the metal oxide is formed. If it reacts with cold water, you get the metal hydroxide. Calcium, strontium and barium These all react with cold water with increasing vigour to give the metal hydroxide and hydrogen. Strontium and barium have reactivities similar to lithium...
