Explain why there is a general increase in the first ionisation energy across the third period.
(a(ii))[2]
On the graph, show where the ionisation energies of the two elements that come before Mg in this sequence should be placed.
(a(iii))[4]
Explain, using electron arrangements, the decreases in first ionisation energy between Mg and Al and between P and S.
