Ionisation energies and shells |
1) a) Define the 1st ionisation energy and write the equation for Bromine [4]
b) Write equations including state symbols to represent the:
i) 1st ionisation energy of Li
ii) 3rd ionisation energy of Al
Use the symbol e- to represent electrons [2]
c) What would you notice about the next ionisation energy for (i) and (ii)? Explain your answer using atomic structure. [7]
2) How does the 1st ionisation energy change down group 2 and explain why? [3]
3) Sketch the graph for the successive ionisation energies for Na [3]
4) The successive ionisation energies are shown:
1 |
2 |
3 |
4 |
5 |
1086 |
2353 |
4621 |
6223 |
37832 |
