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 |
a) To which group of the periodic table does this element belong? Explain
