WebThe questions then extend to develop an understanding of the trend in reactivity of Group 2 elements. The second section focuses on reviewing the reactions of Group 2 elements and oxides, and makes some links with the content on acids in Section 2.1.4 of the specification. WebGroup 2 elements react readily with cold water to form a metal hydroxide and hydrogen. The reactions of group 2 metals with water is a redox as Group 2 elements are oxidised from an oxidation state of 0 to +2. Hydrogen is reduced from a +1 state to 0. The group 2 elements form +2 ions with then react with water.
