- b) Drinking water can be obtained by desalination. State what is meant by desalination and name a process by which it can be carried out.
- The elements in group 7 are called halogens. The halogens get less reactive as you go down group 7. Predict which halogen has the most quickly with hydrogen. (Hint: use the periodic table to help you) Enteranswer
- Alkali metals are found in group 1 of the periodic table. Use the periodic table to write down one alkali metal. You should write down the whole name, rather than just the chemical sym Enteranswer
