- EL Group 2 and Writing Balanced Equations CI 1.2 3.1 11.2
- Formula
- State Symbols
- Water is (l)
- Solutions are (aq)
- Group 2
- Reactions of the elements
- Metals react with water to give metal hydroxide and hydrogen.
- Reactions become more vigorous as you go down the group.
- The Oxides
- The oxides react with water to produce an alkaline solution of the hydroxide
- The oxides react with acids and so act as bases
- The Hydroxides
- Become more soluble as you go down the group
- Solutions produced are alkaline since the solutions contain OH- (aq).
- Solutions produced are alkaline since the solutions contain OH- (aq).
- Become more soluble as you go down the group
- The Carbonates
- Become less soluble as you go down the group
- The carbonates undergo thermal decomposition on heating to give the metal oxide and carbon dioxide
- Thermal stability increases down the group.
- Reactions of the elements
