Question 12
1. In groups, develop a model to show the structure of an atom as in Figure 4.8. You can use toothpicks and modelling clay of three colours, cotton wool or string and so on.
2. Discuss what materials you will use.
3. Choose an element. Pick one from the Periodic Table. Note the number of protons, neutrons and electrons it has.
4. Build the nucleus, showing the correct numbers of neutrons and protons.
5. Arrange the electrons around the nucleus. Remember to add them in the correct shells.
6. Label the chemical symbol, proton, neutron and electron on your model. For instance, you can write the labels on separate pieces of paper and stick the pieces of paper on the model.
7. Present your model to the class.
